Class 11 Biology Important Chapters for NEET

In this article, we are going to highlight the key topics for NEET 2022 Preparation in Biology Class 11 based on their weightage.

In India, the National Eligibility Entrance Test (NEET) is among the most challenging tests in the field of medicine. Over lakhs of candidates take the NEET to gain admission to the best medical colleges, such as AIIMS and JIPMER. The NEET 2022 cut-off is incredibly high, so a few students are able to get into MBBS programs after passing.

The NEET consists of three subjects: Chemistry, Physics, and Biology. The theoretical question pattern of Biology makes it easier to score. The Biology segment consists of five units and multiple chapters. To score well in this subject, students need to prepare strategically and focus on the key topics. This guide will provide an overview of the complete NCERT Class 11 NEET 2022 Biology syllabus if you are not familiar with those chapters.

A variety of topics is introduced in CBSE Class 11 Biology that is essential for understanding higher-level concepts in Class 12. A strong emphasis is placed on Class 11 Biology topics in the NEET test. The CBSE class 11 Biology subject is therefore important for the class 12 and NEET exams.

NCERT Class 11 Biology Syllabus for NEET 2022

NTA (National Testing Agency) prepares the syllabus for NEET 2022 every year. According to NTA’s latest release, the authorities will follow the same syllabus in 2022.

An overview of the Class 11 Biology syllabus for NEET 2022 is provided below.

  • Unit I: Diversity of Living Organisms
  • Unit II: Structural Organisation in Animals and Plants
  • Unit III: Cell: Structure and Function
  • Unit IV: Plant Physiology
  • Unit V: Human Physiology

To get brilliant scores, students should focus on chapters that have the highest marks. In order to meet NEET 2022 eligibility criteria for MBBS admission, the chapters listed above should be given priority. The most important topics should be covered first, and then the less important ones can be addressed. For NEET 2022, if time is limited, studying the above chapters may yield good results.

As a summary, the NEET 2022 Class 11 Biology syllabus is composed of five chapters and twenty-two units. It is important to understand what happens to cells, how they divide, and how they cycle through. It is also important to understand how plants move and how they move as well as the structure of flowers. To score high marks in the upcoming NEET 2022 examination, students must learn and revise these Biology syllabus topics.
