NEET BOTANY PREPARATION AND STUDY PLAN 2021, 2022, 2023

Botany Overview

Biology comprises of botany and zoology
Botany is the branch of biology concerned with the scientific study of plants. ... However, advances in our knowledge about the myriad forms of life, especially microbes (viruses and bacteria)
Both of the subjects carries 45 questions comprising of 360 marks , therefore the aspirants should provide equal efforts to these subjects.

Students should get thorough with the topic of Biology since Class 11 as the syllabus carries equal distribution of questions from Class 11 and Class 12.
Preparation for NEET Biology requires a candidate to be thorough with the NCERT as the syllabus and questions for the Biology are almost entirely based on it. Analysis of NEET previous year question papers has proved that the difficulty level of the question paper has increased over the years.

Botany - Important Topics

Based on the weightage and the frequency of questions over the years, the important topics for preparation of botany can be listed as :-
• Physiology – Plant
• Reproduction – Flowering Plants
• Plant Diversity
• Ecology
• Structural Organization in Living Organisms
• Cell Structure and Function
• Genetics

In these chapters, Genetics carries the highest marks, therefore students should give more focus on genetics. Students should also practice numerical which has been asked from this chapter which includes the pedigree charts .
To learn about plant physiology , students should take helps of diagram for better understanding.
Plant diversity should be learnt with the help of flow charts and tables.

Prepare tables and flowcharts:

The best way to learn Botany is with the help of charts and tables, that will help in quick revision strategy before your exam days.
The classification of plant kingdom should be learned through the pneumonic which are also given in the notes and also covered in video lectures provided by the teachers. Try and include important applications and examples in these charts. As the notes provided by KAYSONS EDUCATION includes pie charts, diagrams, tables to memorize easily and understand the concept.

Practice and repeat learning:

Aspirants preparing Biology for NEET 2020 must develop the habit of intense practice. Practice will also help in learning the concepts. Practicing more number of NEET sample papers and previous year question papers should be solved to get an idea about the pattern of questions that will be asked. You should practice the Question provided in the end of the chapters to clear the concepts about the topic.

Attend the mock tests:

Aspirants should, take up as many mock tests as possible to enhance their preparation for NEET Biology. The student should attend each and every level of test conducted by KAYSONS EDUCATIONS. It includes chapter level test, unit level test and subject level test. This institution provides you a test series to the students who performs better in these tests named Doctors Paradise and Doctors Material.

Doubt clearance regularly:

The aspirants should clear their doubt regularly. Kaysons Education provides you the facility to clear you doubts at each level when you are preparing and solving the questions. One more facility is added to the package that you can also see the doubts asked by the other students and you can clear it at that time only.

Revise Regularly:

To get the proper benefits of studying and practicing one should keep revising at regular intervals. This will help in the memorizing. Candidates should make it a point to revise the entire syllabus several times before the exams so as to be thorough with each concept included in each topic. When one student do regular revision, one can keep the track of the progress of the study

 

Unit-1: The Living World

Introduction:

Life can be defined as a unique aggregation of molecules. These molecules have the tendency to express themselves through various reactions collectively called metabolic reactions. The basic purpose of these reactions is to transform or produce and utilize energy. The term used to define these reactions in a cumulative way is metabolism. Through metabolism, various biomolecules are synthesized resulting in growth, development, responsiveness, adaptations and reproduction. The forms that possess and express all these features are called Living beings. These living being live in almost all possible habitats like forests, mountains, deserts, oceans, freshwater bodies, hot springs, polar regions etc. They are linked to one another by sharing the common genetic material. All living beings share characteristics like organization, energy utilization, regulation or homeostasis growth, development, reproduction and adaptation.

Paper Analysis:

The Living World happens to be a low-weighted chapter with only 6 questions being asked in the past 11 years. On an average, we can expect 1 question at max from this particular chapter, it being a simple one. There has been irregularity in the appearance of questions in the question paper. No question came for continuous years in 2014 and 2015, while before that, the question appeared alternatively every year. The last two year has seen one question being asked each time so there is a fare chance of a question being asked in the coming paper.
The important topics to be covered from this chapter are
• Taxonomy and Systematics
• Characteristics of Living Organisms
Below is the Bar-Graph depicting the number of questions asked in the last papers.

Tips and Tricks:

Since this chapter has a relatively low weightage in NEET papers, this chapter needs to be finished quickly and precisely.
The following tips might help you out:
• Reading NCERT shall be the first stop towards covering this chapter. That will make the students concept crystal clear. Here is the link for the NCERT PDF version of the chapter:
• Making a mind map of the chapter will clearly help the students in revision. Making Flash cards will also be beneficial.

• Along with the above points, students must practice adequate number of questions from this chapter.
• Revision once a fortnight is a must so that one does not forget the core of the chapter.

Unit-2: Structural Organization in Plants

 Morphology

Introduction:

Morphology is the branch of biological science that deals with the study of form, size, color, structure, and relative position of various parts of organisms. Knowledge of morphology is essential for recognition or identification of plants, and it also gives information about the range of variations found in species. Deficiency and toxicity symptoms are morphological changes that occur in response to shortage or excess of minerals, and this is covered by morphology.

Chapter Analysis:

Morphology was one of the most frequented topics in the NEET Syllabus. A total of 39 questions have been asked in the past 11 years. However, a sharp decline has been observed in the past three years where only 5 questions have been asked combined. This shows that the paper setter have moved to other vast topics for questions. Nevertheless, 7 questions were asked in 2012 while 6 were asked in 2016. So, it will not be a bad choice to expect 2-3 questions in the coming paper.
The following bar-graph shows the frequency of questions asked in the previous years:

The following are the important topics to be covered from this chapter :
• Parts of Flowering Plants – Roots, Stems, Leaf, Flower and Seed
• Families of Flowering plants

Tips and Tricks:

Students must make sure that they have understood the functions of the various parts of the flowering plants as well us have thorough knowledge of the families of them. The following tips might help in the retention of the read study material in their memory :
▪ The students must begin with reading the NCERT portion as it has a good basic explanation of the chapter and helps form the base for further reading. Here is the link to the NCERT PDF version of the mentioned chapter :

▪ Mnemonics may be created uniquely by the student so that they are able to retain the parts in their mind easily.
▪ All the past year questions must be solved.
▪ Revision every week should be done to keep the chapter fresh.

 Antomy of flowering plants

Introduction:

Anatomy refers to the study of internal morphology or form and structure of the internal parts like bones, organs etc. However, in the case of flowering plants, it implies the general term for the study of the internal structure of plants. It is also known as Phytomy. The most important part of the plant structure is the tissue. A tissue may be defined as “a group of similar or dissimilar cells having common origin and performing a specific function.” Tissues are mainly divided into three categories: Meristematic tissues, Permanent Tissues and Secretory tissue.

Chapter Analysis:

Anatomy is another chapter with an even number of questions being asked each ever. Collectively, 35 questions were asked in the last 11 years, with 5 question being asked in each 2009 and 2012. Except for the year 2014, where only 2 questions were asked, atleast 3 or more questions have been asked in the paper. So, 3 questions can be expected to be present in the paper from Anatomy.
The following bar-graph exhibits the frequency of questions asked in the last 11 years :

The important topics to be covered from this chapter are :
▪ Anatomy of different types of flowers
▪ Types of Tissue Systems

▪ There is a huge number of unique terms and keywords. Hence, they must be revised regularly. Once in a fortnight is a must.
▪ The diagrams must be practiced and understood clearly. Video explanations can be looked onto if one finds difficulty in understanding the diagram.

Unit-3: Cell Biology

Introduction:

Cell Biology is a branch of biology that studies the structure and function of the cell, which is the basic unit of life. Cell Biology is concerned with the physiological properties, metabolic processes, signaling pathways, life cycle, chemical composition and interactions of the cell with their environment.

Syllabus

Environmental issues: Air pollution and its control; Water pollution and its control; Agrochemicals and their effects; Solid waste management; Radioactive waste management; Greenhouse effect and global warming; Ozone depletion; Deforestation; Any three case studies as success stories addressing environmental issues.

Chapter Analysis:

With a total of 39 question being asked in the past 11 years, this chapter happens to be one of the most important chapters from the NEET Syllabus. Only once in the past 11 years has the question count fallen below 3, i.e. in 2017. Other than that, all the other years have had at least 3 questions. The past two years had 7 question being asked. So, we should be expecting at least 3-4 questions from this chapter in the coming paper. The below mentioned graph illustrates the analysis given above:

The important topics to be covered from this chapter are:

Unit-4: Plant Physiology

Chapter-2: Mineral Nutrition

Introduction:

Every living organism need carbohydrates, proteins, fats, water, and minerals to live. Similarly, plants and nutrients for growth and development. The study of the minerals that the plant requires for sufficient and sustainable growth is known as Mineral Nutrition. The techniques used to study the mineral requirement of plants are:
1. Hydroponics: A technique in which plants are grown in nutrient solution instead of soil. This technique is used at the time of commercial production of vegetables. It is also used to study the mineral deficiency diseases in plants.
2. Aeroponics: The technique in which nutrients are sprayed suspended in the air.
Different plants have different mineral requirements. There is criterion for the essentiality of an element.

Chapter Analysis:

Mineral Nutrition was an important topic and fair number of questions were asked from this chapter during 2009-2012. However, after 2012, no paper has accounted for more than two questions from Mineral Nutrition, with the paper coming in 2017 and 2019 having no questions from the chapter. The popularity of Mineral Nutrition among the paper setters has decreased significantly, and hence one cannot expect more than 2 question in the coming exams.
The following Bar-Graph exhibits the frequency of question asked in the past years:

The important topics to be covered from this chapter are:
• Essential Minerals
• Macro and Micronutrients and their role
• Deficiency and their Symptoms

Tips and Tricks:

Since Mineral Nutrients turns out to be a low-weighted chapter, one must not spend a large amount of time in this chapter. Smart work is required so that the chapted is completed within a short interval of time and it yields optimum result:
• If one gets through with NCERT, one is not required to look through other books for understanding this chapter. Hence, NCERT is of utmost importance. Here is the link to the NCERT PDF version of the chapter.
• Mnemonics must be created of the various nutrients essential for the plants so that they are retained easily in the memory.
• Revision once a month or 20 days will be adequate as this is not a vast chapter.
• The past year questions must be done clearly with high precision, and they must be at the student’s fingerprints.
• Practice a large number of questions from this topic and leave no stones unturned to make this chapter one of your strengths.

Chapter-3: Photosynthesis in higher plant

Introduction:

The process of synthesis of organic food (carbohydrates) from CO2 and water in the presence of sunlight is called photosynthesis. All green plants have the capacity to make food by photosynthesis. It is the most important synthetic process on earth because it is the only source of carbohydrates in which solar energy is fixed in the form of chemical energy. During photosynthesis, the kinetic energy (light energy) of sunlight is transformed into chemical energy and stored in carbohydrate molecules. This chemical energy is used for the growth and sustenance of our biosphere. All animals including human beings depend on plants for their food. Various experiments are carried out to prove the elements required for photosynthesis like Variegated Leaf Experiment, Light Screen Experiment, Mohl’s Experiment etc.

Chapter Analysis:

This is a medium weightage chapter with questions being regularly asked. However, the last year’s paper did not include any question from Photosynthesis. A total of 20 questions have been put cumulatively in the paper held over the last 10 years. 2016 saw a hike in the number of questions asked, with 4 questions being asked. Since the questions are asked frequently, we can expect at least 1-2 questions from this chapter in the coming paper.
The below given bar-diagram represents the number of questions asked year-wise :-

The important topics to cover in Photosynthesis is :
• C3 Cycle
• C4 Cycle

Tips and Tricks:

2. One must read the C3 and C4 Cycles separately and sincerely as it is the most important topic of the chapter.
3. The entire cycle must be read sufficient number of time and similarities must be brought out between the two cycles, making them easier to remember.
4. The past year questions must be solved at once.

Chapter-4: Respiration in plants

Introduction:

Respiration is the process in which complex organisms are combined with oxygen and are broken down to simpler substances with consequent release of energy and production of carbon dioxide and water. The term respiration was first coined by Dutrochet. The breaking down of C-C bond of complex molecules by oxidation leading to the release of a lot of energy is called cellular respiration. Plants breathe and they require oxygen for the respiration and gives out CO2. Plants don’t have any special system for breathing or gaseous exchange. Stomata and lenticels allow gaseous exchange by diffusion. Only a very little transport of gases takes place from one part to another in plants.

Chapter Analysis:

This is a low weighted chapter with only a few questions asked each year. In all, 11 questions have been asked in the last 11 years, averaging at one question per year. However, no questions were asked in 2015, 2012 and 2011. However, in the last three years a total of 5 questions have appeared making the chapter tentative to exhibit a question or two in the coming paper. Hence, it will be not foolish to expect at least 1 question in the coming paper from Respiration in Plants.
The below mentioned graph shows the frequency of questions asked in the previous 11 years :

The important topics to be covered from Respiration in Plants are :
• Glycolysis
• Krebs Cycle
• Respiratory Quotient

Tips and Tricks:

Since this is a low weighted chapter, this chapter must be done at once and should be given periodic revision. The following points might help:

2. Adequate amount of questions must be solved in relation to respiratory quotient as it is easy as well as mark scoring topic.
3. Glycolysis and Krebs Cycle must be given periodic revision, once every fortnight.
4. Past year questions must be solved sincerely with utmost perseverance.

Chapter-5: Plant Growth

Introduction:

All cells of the plant develop from the zygote. The development of a mature plant from the zygote follow a precise and highly ordered succession of events. It is actually the sum total of growth and differentiation. A complex body organization is formed during this process. The body produces roots, leaves, branches, flowers and seeds and after that the plant dies. An irreversible permanent increase in size of an organ or its parts or even of an individual. One of the most fundamental characteristics of living things is their ability to grow and develop. A mature plant consists of numerous cell types because all the cells do not grow and develop in the same way. Plant growth is generally indeterminate. In plants growth occurs by cell division and cell enlargement.

Chapter Analysis:

This is a low weighted chapter with the questions being asked irregularly over the course of last ten years. Only 15 questions have been picked from this chapter to appear in the paper, averaging roughly around 1.5 question per paper. However, the paper of 2014 witness 4 questions from Plant Growth. On the other hand, most of the times, the number of questions asked has stayed below 2. The last year saw just one question being asked, and the coming paper can be expected to be no different. Hence, it will be good to expect 1 question from this topic in the coming paper.
The following bar-graph shows the number of questions asked in the past 10 years:

The important topics to cover from the chapter Plant Growth are:
• Plant Growth Regulators
• Photoperiodism
• Differentiation of Plants

Tips and Tricks:

As this is a low weighted chapter, one cannot give much time in the preparation of this chapter, and hence, the chapter must be completed through smart work rather than hard work. The following tricks might prove out to be helpful :
1. One must dive into NCERT first, and cover it thoroughly so that the base is set. Here is the link to the NCERT PDF version of the topic.
2. The topics such as Plant Growth Regulators and Photoperiodism must be covered thoroughly. If one fails to understand it by reading NCERT, one must consult video lectures with interactive dynamics.
3. Flash Cards must be created for this topic, as time by time revision will keep everything afresh.
4. The past year question must be solved.
5. Questions given at the end of the NCERT chapter must be read thoroughly, and the explanations must be pondered over again and again.

Unit-5: Reproduction in Plants

Introduction:

The plants in which the sex organs are carried within the flowers and the seeds are enclosed in a fruit are called angiosperms. Angiosperms are commonly known as flowering plants. The flowering plants reproduce by ‘sexual reproduction’ method. This means that two sexes are involved in reproduction in flowering plants. Like human beings, plants have also male and female sex organs, though they are different in form from humans. The sex organs (or reproductive organs) of a plant are in its flowers. In other words, flowers contain the sexual reproductive organs of a plant. The function of a flower is to make male and female gametes and to ensure that fertilization will take place to make new seeds for the reproduction of plant. Sexual reproduction is the most common method of reproduction in flowering plants. A flower makes both male and female gametes needed for sexual reproduction in plants.

Chapter Analysis:

Now here comes one of the most frequented chapters for NEET – Reproduction in Flowering Plant. All in all, this chapter has provided 45 question cumulatively in the last 10 years, averaging above 4 questions per year. Last year saw a hike in the number of questions asked with a total of 6 question being asked. Except for 2016, each year has seen more than or equal to 3 questions being asked, hence this is one of the chapters which must be prepared sincerely. So, it will be a good estimate to expect 5-6 question in the coming paper.

5. Practicing the previous year question paper is a must so that one gets acquainted with the type of question which can be expected in the coming paper.

Unit-6: Genetics

Chapter-1: Heredity and variation

Introduction:

Heredity is a process of transmission of traits from parents to their offspring’s either via asexual reproduction or sexual reproduction. These characteristics or traits are located on the chromosomes in the form of genes. The differences that are shown by the individuals of a species and also by the offspring of same parents are referred as variations. Variations may be harmful, useless and useful. Harmful or useless variations make individuals unfit for the struggle for existence whereas the useful variation is quite significant and make organisms fit in nature.

Chapter Analysis:

This is another of the heavyweight chapters, having grossed a total of 46 questions over the last 11 years. In 5 years out of the 11, more than 5 questions were asked. Hence, it is one of the most important chapter with respect to NEET Biology. Last three years had 16 question asked in total. So, we can easily expect 5-6 questions in the coming papers.
The following bar-graph depicts the year-by-year question analysis over the past 11 years:

The most important topics to be covered in this chapter are:
• Mendel’s Law of Inheritance
• Sex Determination Numericals

Chapter-2: Molecular Basis

Introduction:

DNA (Deoxyribonucleic Acid) is double helical structure that was cracked by Watson and Crick based on the X-Ray crystallography results. Each strand of a DNA helix is composed of repeating units of nucleotides. Nucleotide consists of 3 components; ribose or deoxyribose sugar, nitrogenous base (purines or pyrimidines) and phosphate. There are two types of purines – adenine and guanine Two polynucleotides chains wrap around each other, where the backbone is constituted by sugar – phosphate and bases project inside. The two DNA chains are antiparallel to each other.

Chapter Analysis:

Molecular Basis along with Heredity forms the most scoring chapters in NEET. A total of 48 questions have been taken from the chapter Molecular Basis in the past 11 years. In the last three years alone, 18 questions were asked. Only twice in the 11 years, i.e. in 2011 and 2013, the question count from Molecular Basis of Evolution dipped below 4, while on three occasions it was 6 or above. Hence, it will not require rocket science to expect at least 5-6 questions in the coming paper.

Chapter-2:Microbes in human welfare

Introduction:

Microbes are beneficial as well as detrimental to the welfare of human beings. Microbes are utilized in many ways for human beings. These microscopic organisms produce half the oxygen in the world. Many types of fungus and other microbes release enzymes that digest dead stuff. They are more than half of the living biomass on the planet. In human body, 9 out of 10 cells are microbes. Microbes are everywhere on our body, in homes, far below the earth’s surface and up to the atmosphere, in cold, cool, warm and hot and very hot places, and even in places without oxygen. Microorganisms always live in water. They can eat all sorts of things, including oil, rocks, dead and living plants and animals.

Chapter Analysis:

The pattern in the number of questions asked in NEET from Microbes is a really uneven one and there have been regular rise and fall in the number of questions asked. All in all, a total of 27 questions have been asked in the past 11 years. However, the last year saw an abrupt increase in the number of questions being asked with 6 questions. Also, in the year of 2012, an enormous 7 questions were asked. However, on other side, the number of questions in the other years have remained 3, limiting to 0 in 2015 and 2009. Hence, making a wild guess, we can estimate 2-3 question being asked in the years to follow.

Unit-8: Ecology and Environment

Chapter 1:Organisms Ans Its Populations

Introduction:

Ecology is the branch of science that deals with the relationship between the organism and the environment. There are different levels of organization, such as:
• Organism – each individual of the species
• Population – It is defined as group of organisms that can interbreed
• Communities – Different population combine to form communities
• Biomes – Large unit of flora and fauna in a specific climatic zone
All the organisms have the ability to adapt via the process of biological variation in order to adjust with their environment. It is adaptation that enhances the ability and chances of survival. Adaptation vary among species but has the common objective i.e. adjustment to variation. For example, polar bears possess several key characteristics and trait that make them capable of adjusting with the harsh conditions of life in Antarctica.

Chapter Analysis:

This is a medium weighted chapter. All in all, 29 questions have been put forward in the question paper spanning over the last 5 years. There is a unique trend in the number of question appearing in paper from Organisms and its Population. Every alternate year, 4 question come and going by that patter, we can expect 4 question in the next year. However, we cannot judge anything practical from pattern when it comes to prestigious examinations like NEET, and hence, an apt analysis gives the result that 2-3 question can be expected in the coming year’s papers. The following bar-graph gives the year-by-year number of question coming from Organisms and its Population. The pattern which was discussed in the above paragraph can be observed, except for one.

The important topics to be covered from this chapter are:
• Organisms and its Environment
• Graphs of Population Growth

Tips and Tricks:

1. NCERT must be read properly for this chapter as it covers most of the topics briefly. Here is the link to the NCERT PDF version of the chapter:
2. The Graphs of Population Growth must be looked at least once a day so that it is fresh. There have been papers where questions were directly asked from these graphs.
3. Practice a large number of questions from this topic and leave no stones unturned to make this chapter one of your strengths.
4. Online video lectures might help the student in having a clearer understanding of the topic.

Chapter 2:Ecosystem

Introduction:

An ecosystem is complex set of relationships among the living resources, habitats and residents of an area. It includes animals, plants, trees, birds, fish, water, soil, micro-organisms and people. In other words, an ecosystem comprises of all the living things in a given area, whereby they interact with each other and their non-living environment (such as soil, climate, water, earth, weather, etc.). Ecosystem can be huge as it may comprise of different plants and animals, or can be in particularly harsh places of the world. Ecosystem, at the basic functional level, contains primary producers which are capable of harvesting energy via photosynthesis. Next are the consumers and these consumers can be primary consumer. Decomposers work at the bottom of food chain.

Chapter Analysis:

Ecosystem turns out to be a low weightage chapter with roughly 30 questions asked in the last 11 years. Most of the times, the number of questions asked stays less than 3. However, in the year 2015 and 2012, 6 questions were asked making it a deal breaker. In the other years, most of the time 2 questions were asked. Hence, we can estimate at least 2-3 question to come from Ecosystem
The below given bar-graph plots the number of questions asked per year over the last 10 years:

The important topics to cover from Ecosystem are:
• Energy Flow
• Pyramids of Number, Biomass, and Energy
• Nutrient Cycling (Carbon and Phosphorus)
• Ecological Succession

Tips and Tricks:

This chapter has happened to be the deal breaker in 2015 and 2012, so one must devote adequate time on this chapter and play it to his/her strength. The following points might be helpful:
1. Reading the NCERT is a must for this chapter. Here is the link to the NCERT PDF version of the chapter:
2. Biome Distribution Graph must be understood clearly along with its labelling.
3. One must be thorough with the topics such as Population Growth Curve, Population Density and related factors.
4. One must make cheat sheets for the names of components of ecosystem, definitions, formulae and units.
5. Inverted Biomass Pyramid, being a strange topic, must be covered thoroughly.
6. Practice a large number of questions from this topic and leave no stones unturned to make this chapter one of your strengths.

Chapter 4:Environmental Issues

Introduction:

Population is any undesirable change in physical, chemical or biological characteristics of air, land, water or soil. Agents that bring about such an undesirable change are called as pollutants. In order to control environmental pollution, the Government of India has passed the Environment (Protection) Act, 1986 to protect and improve the quality of our environment. We have various sources of pollution such as Gaseous Emissions, Industrial Smoke, Domestic Sewage, Industrial Effluents, Biomagnification, Eutrophication etc. This pollution causes various important atmospheric effects such as Ozone Layer Depletion, Deforestation, Bank Erosion etc. making the future of Earth a really dark period.

Chapter Analysis:

Although the last paper had 6 question from Environmental issues and the year of 2009 had 8 questions, other years have not got many questions from this chapter. Most of the time, the question count from this chapter stayed less than 4. However, on those two occasions it proved out to be game changing. All in all, 40 question have been asked in the 11 years. So, we can expect at least 3 questions from this chapter in subsequent papers. This is a medium weightage chapter.
The following bar-graph exhibits the number of questions asked each year:

The important topics to cover from Environmental Issues are:
• Air Pollution and its Control
• Water Pollution and its Control
• Agrochemical and their effects
• Solid Waste Management
• Radioactive Waste Management
• Greenhouse Effect and Global Warming
• Ozone Depletion
• Deforestation

Tips and Tricks:

1. One should always start reading NCERT in the beginning of this chapter as it has very briefly explained each and every issue. Here is the link to the NCERT PDF version of the chapter:
2. Since this chapter has been game breaker in few NEET papers, one must give proper revision to this chapter every fortnight.
3. The past year questions must be attempted by the students so that they are acquainted with the type of question being asked in papers.
4. One must create separate Flash cards for the different types of Pollution, which shall make the revision of the topic easier.
5. One must remember the exact chemical compounds responsible for the different environmental effect.
