Top Five Highest Weightage Chapters in the Biology section of NEET

There are a total of 90 questions in the Biology section of the NEET exam, with a weightage of 360 marks. The questions are distributed across various chapters of the Biology syllabus. Here are the top five highest weightage chapters in the Biology section of NEET:

1. Human Physiology
- Human Physiology is one of the most important chapters in the Biology section of NEET, covering topics such as digestion, respiration, circulation, excretion, and reproduction in humans.
- This chapter holds a significant weightage in the exam, as it covers vital processes and functions of the human body.
- Key topics include the structure and functions of organs like the heart, lungs, kidneys, and reproductive system.
- In this chapter, students are required to have a deep understanding of the concepts, processes, and mechanisms involved in human physiology.

2. Genetics and Evolution
- Genetics and Evolution is another high-weightage chapter in the NEET Biology section.
- This chapter covers the principles of inheritance, genetic variations, DNA replication, mutation, and mechanisms of evolution.
- Key topics include Mendelian genetics, chromosomal disorders, population genetics, and the Hardy-Weinberg principle.
- Students should focus on understanding the concepts of genetics, inheritance patterns, and the factors contributing to genetic variations.

3. Cell Structure and Function
- The Cell Structure and Function chapter covers the basic unit of life, the cell, and its various components.
- Topics such as the cell theory, cell organelles, plasma membrane, and cell cycle are covered in this chapter.
- A strong foundation in cell biology is crucial for understanding the functioning of all living organisms.
- Key topics to focus on include the structure and functions of organelles like the nucleus, mitochondria, endoplasmic reticulum, and Golgi apparatus.

4. Plant Physiology
- Plant Physiology is an important chapter that focuses on the functioning and processes in plants.
- Topics covered include photosynthesis, plant growth and development, mineral nutrition, and transport in plants.
- Students should have a clear understanding of the mechanisms and factors influencing plant growth, photosynthesis, and nutrient uptake.
- Key topics in this chapter include the structure and functions of plant tissues, absorption of water, and the role of hormones in plant growth.

5. Reproduction
- The Reproduction chapter covers both sexual and asexual modes of reproduction in plants and animals.
- Topics such as the reproductive system, gametogenesis, fertilization, and embryonic development are included in this chapter.
- Students should focus on understanding the reproductive processes, hormonal control, and the development of gametes and embryos.
- Key topics to focus on include the male and female reproductive systems, menstrual cycle, fertilization, and embryogenesis.

These five chapters hold the highest weightage in the Biology section of the NEET exam. Students should dedicate sufficient time and effort to thoroughly understand these topics and their associated concepts and mechanisms.
