NEET Biology Important Questions From The Unit – The Living World

The NEET Biology syllabus has two sections, botany, and zoology. To cover the entire NEET Syllabus, students must study Class 11 and Class 12 Biology NCERT textbooks and NCERT Solutions. Also, selecting and preparing for the most frequently appearing NEET Biology questions is essential to score the maximum marks. The chapter The Living World comes under the first unit of Class 11 NCERT Biology. This chapter carries 2% weightage in NEET Biology. Every year, at least one question appears in the NEET Biology question paper from The Living World chapter.

Question 1. Animals, dogs and mammals represent.

Answer. Taxa at different levels.

Question 2. The first step of taxonomy is?

Conclusion

Most of the questions from the first unit of Class 11 Biology are straightforward, and there are no tricky questions. However, many are statement-based questions from the NCERT Class 11 Biology book. Therefore, students must carefully review the chapter to cover all important concepts and terminologies. 

Although the questions are moderately easy, students must go through the NCERT solutions to practise the important questions that are likely to appear in the NEET. In addition, practice questions from the NEET Previous Year Question Paper. Finally, another effective way to ensure your score is high enough to meet the NEET Cut-Off is by opting for NEET Mock Tests.
