Chapter-1: The Living World
Diversity in the Living World is the first Unit in the NEET Biology Syllabus and lays the foundation of fundamental classifications and understanding. Due to its necessity as the bedrock, it is an important chapter which enables progress on much broader concepts later on in other units. It is very important to be thorough with the salient features and classifications. We, at Kaysons, have analysed the previous year papers and added tips and tricks for this unit as well as for the rest two.
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.
• All questions from the past 10 years NEET paper must be covered.
• 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.
Biological Classification is defined as the process of grouping the organisms according to certain similarities. Linnaeus proposed the two kingdoms of classification. He classified organism into animal kingdom as Animalia and plant kingdom as Plantae. There were certain limitations associated with two kingdom classification such as it did not differentiate between eukaryotes and prokaryotes, unicellular and multicellular organisms, and photosynthetic and non-photosynthetic organisms. Hence, further development was made in this field with the Five Kingdom classification being the prime one, being created by R.H. Whittaker.
This happens to be a medium to high weighted chapter with questions appearing in all the previous 10 years of examination. A total of 40 questions have been asked in the last 10 years. Astonishingly, 8 questions were asked in the year 2011 and 6 questions in the year 2014. On most of the occasions, above 3 questions were asked in the paper. However, only one question was asked in the previous year. So, the conclusion is that we can expect at the least 3-4 questions in the coming papers.
Below is the Bar-Graph analysis of the number of questions asked in the previous years:
The most important topics to be covered in this chapter are :
• Two Kingdom Classification
• Five Kingdom Classification
Tips and Tricks:
Since this is a high weightage chapter, one must devote adequate time to this. There must be no negligence in completing this chapter as this might be the one chapter to help you score heavily. The following tips might be helpful to the students:
• NEET Syllabus has its base in the NCERT Textbooks and this chapter is well explained in that. So, the student must be thorough with the material present in the NCERT Book. Here is the link to NCERT PDF version of the chapter :http://ncert.nic.in/textbook/textbook.htm?kebo1=2-22
• This chapter is filled with small details and keywords. Hence making Flash Cards will be the best way to keep them to your memory.
• The past year questions must be practiced a number of times so that they should be on your fingers.
• Practice a large number of questions from this topic and leave no stones unturned to make this chapter one of your strengths.
• Revision every week will be appreciated as the different terms and keywords are quite likely to slip out of the mind if not revised periodically.
Whittaker classified the whole living organism into five kingdoms on the complexity of cell structure (Prokaryotic and Eukaryotic), complexity of body (unicellular and multicellular) and mode of nutrition (autotrophs and heterotrophs). One among them is the Kingdom Plantae, which includes green, brown and red algae, liverworts, mosses, ferns and seed plants with or without flowers. They have the following characters: Multicellular organisms with walled and frequently vacuolate eukaryotic cells. They contain photosynthetic pigment in plastics. Principle mode of nutrition is photosynthesis but number of plants has become absorptive. Primarily non-motile, living anchored to a substrate.
This is another moderately weighted chapter with questions being asked consistently, with 33 questions being asked in the last 11 years. While only one question was asked the previous year, 4 questions were asked each in 2017 and 2018. There is an abrupt decline in the number of questions asked in 2011, where it tends to 1, while in other papers, at the least 2 questions have been asked. So, we can roughly estimate 3 questions to be asked from this chapter.
The important topics to be covered from this chapter are :
• Salient Features and Classification of Plants – Algae, Bryophytes, and Pteridophytes
• Salient Features of Gymnosperms and Angiosperms
The bar-graph below exhibits the frequency of the number of questions asked in the previous year papers:
Tips and Tricks:
This chapter happens to be another important chapter with moderate number of questions being asked. Hence, it is important for the students to make this chapter one of their strengths. For this, the following tips might help:
• The students must be through with the NCERT study material as it forms the base for further understanding. Here is the link for the NCERT PDF version of the chapter :
• Again, this chapter involves large number of keywords and terms. Hence Flash Cards help.
• One must make a large flow chart of the various classification and look at it regularly.
• The past year questions must be solved a fair number of times so that one understands the type of questions asked.
• Regular revision of this chapter is of utmost importance as the vastness of the syllabus will make the mind forget the key terms easily.
