Chapters in Zoology and Botany Frequently Repeated in NEET Exams

Zoology:
1. Human Physiology: This chapter is one of the most important and frequently repeated topics in the NEET exam. It covers various systems of the human body such as the circulatory, respiratory, digestive, excretory, nervous, and reproductive systems. Students should have a thorough understanding of the structure, functions, and regulatory mechanisms of these systems.

2. Genetics and Evolution: This chapter focuses on the principles of Mendelian inheritance, chromosomal theory of inheritance, DNA replication, gene expression, genetic disorders, and the mechanisms of evolution. Questions related to genetic crosses, pedigrees, mutations, and evolutionary patterns are often asked in the NEET exam.

3. Cell Structure and Function: This chapter deals with the microscopic structure and functions of cells. Topics such as cell organelles, cell division, cell cycle, and cell signaling are frequently asked in the NEET exam. Students should have a good understanding of the structure and functions of cell membranes, mitochondria, endoplasmic reticulum, Golgi apparatus, and nucleus.

Botany:
1. Plant Anatomy: This chapter focuses on the study of the internal structure of different plant organs such as roots, stems, leaves, and flowers. Questions related to tissues, their types, and functions are frequently asked in the NEET exam. Students should be familiar with the arrangement of tissues in the vascular bundles, leaf anatomy, and floral modifications.

2. Plant Physiology: This chapter covers the various physiological processes occurring in plants, including photosynthesis, respiration, transpiration, mineral nutrition, and plant growth regulators. Questions related to the mechanisms and factors affecting these processes are commonly asked in the NEET exam. Students should have a clear understanding of the role of chlorophyll, stomata, enzymes, hormones, and nutrients in plant functions.

3. Reproduction in Plants: This chapter deals with different modes of reproduction in plants, including sexual and asexual reproduction. Topics such as pollination, fertilization, seed formation, and fruit development are frequently asked in the NEET exam. Students should have a good understanding of the reproductive structures of plants, floral biology, and the process of seed germination.

Conclusion:
The chapters mentioned above are frequently repeated in the NEET exam. Therefore, it is crucial for students to focus on these chapters and thoroughly understand the concepts and principles associated with them. Regular practice of NEET previous year question papers and mock tests will also help in familiarizing oneself with the exam pattern and question types.
