Botany vs Zoology - NEET Biology Chapter-Wise Weightage Trends (2021-2025)

Why Understanding Botany and Zoology Weightage Matters for NEET?

In NEET Biology, Botany focuses on the study of plants, including their structure, functions, growth, reproduction and evolution. On the other hand, zoology deals with animals, including their anatomy, physiology and health. Most botany questions are direct and NCERT-based, making it a high-scoring area. Zoology requires a clear understanding rather than rote memorisation.

Both sections are equally important and carry their own weightage in the exam. A clear understanding of these two branches helps students connect the concepts and strengthen their overall preparation. By balancing both sections, students can cover the NEET Biology syllabus on time.

NEET Biology Chapter-Wise Weightage Comparison

By understanding the NEET biology chapter-wise weightage, students can prioritise the chapters and plan their study time accordingly. These units not only help you to save time and increase accuracy but also keep you calm and reduce exam stress.

Botany Chapter-Wise Weightage Analysis (Last 5 Years)

The table below provides an analysis of the Botany section from the last five years:

The data is from the last five years, and transport in plants, the Strategies for Enhancement in Food Production and Mineral Nutrition chapters are not in the syllabus now.

It can be observed from the table that the molecular basis of inheritance, biotechnology, cell division, sexual reproduction in flowering plants and genetics dominate the high-weightage chapters.

Zoology Chapter-Wise Weightage Analysis (Last 5 Years)

The table below provides an analysis of the Zoology section from the last five years:

The data is from the last five years, and the digestion and absorption chapter is not in the NEET syllabus now.

It can be observed from the table that the animal kingdom, human health and diseases, human reproduction and structural organisation in animals are the high-weightage chapters and cover almost half of the syllabus of the Zoology section.

Botany vs Zoology in NEET: Most Important High-Weightage Chapters

While NEET Biology carries equal marks for both Botany and Zoology, the high-weightage chapters vary. The table below shows the most important chapters that cover almost 60-65% of the total NEET Biology syllabus. So whether you are short on time or revising the syllabus, these chapters should be on priority.

It can be observed from the table that Botany dominates the high-weightage chapters, as it includes principles of inheritance and variation, and the molecular basis of inheritance. Therefore, start NEET Biology preparation 2026 with Botany chapters to gain confidence and cover a large portion of the syllabus early.

Smart Study Strategy for NEET Biology 2026 Based on Weightage

Now that it is clear which are the most important units and chapters, it is important to prepare a strategy to prepare them effectively.

Follow the NCERT Line by Line

Most of the NEET questions are asked directly or indirectly from the NCERT lines or diagrams. Start by reading the NCERT textbook line by line and highlighting the most important points and definitions.

Revise Through Concept Maps and Flashcards

Concept maps and flowcharts are very helpful in learning the sequence of a process. For example, stages of Prophase I in Meiosis I, which is a frequently asked topic in NEET.

Practice PYQs and Mock Tests

NEET Biology MCQs can be application-based or memory-based. In both cases, solving PYQs and mock tests helps your brain think and memorise the concepts. This ensures high accuracy and improves confidence during exams.

Integrate Botany and Zoology Topics

Study the related topics, such as reproduction in plants and animals, together. This approach helps to build a strong foundation and improve long-term memory for the exam.

Smart Time Allocation

Focus the majority of your study time on these high-weightage units and the remaining on low-weightage ones. Since Botany covers a major part of the syllabus, give priority to those chapters and revise them again and again.

Use Mnemonics

Mnemonics are easy, quick and fun. They can make you learn lengthy topics in a few minutes. Processes that include several steps, for example, the steps of rDNA technology.

NEET 2026 Biology Practice Questions: Botany and Zoology

Test your understanding with these previous year NEET biology questions:

Botany

Q1. Which chromosome in the human genome has the highest number of genes?

Options:

1. Chromosome 10

2. Chromosome X

3. Chromosome Y

4. Chromosome 1

Difficulty: Easy

Explanation:

Chromosome 1 is the largest human chromosome and carries the most genes of all the chromosomes. It has more than 2,000 protein-coding genes that play a wide variety of fundamental biological functions. Chromosome X also carries many genes, particularly for sex-linked characteristics, but not as many as chromosome 1. Chromosome 10 has fewer genes than chromosome 1, and "Chromosome Y" has fewer than 100 genes. Thus, chromosome 1 has the most genes in the human genome.

Hence, the correct answer is option 4) Chromosome 1.

Q2. Which of the following statements is correct regarding the process of replication in E.coli?

Options:

1. The DNA dependent DNA polymerase catalyses polymerization in one direction that is 3' to 5'

2. The DNA dependent RNA polymerase catalyses polymerization in one direction, that is 5' to 3'

3. The DNA dependent DNA polymerase catalyses polymerization in 5' to 3' as well as 3' to 5' direction

4. The DNA dependent DNA polymerase catalyses polymerization in 5' to 3' direction

Difficulty: Easy

Explanation:

In prokaryotic organisms such as E. coli, the process of DNA replication is carried out by DNA-dependent DNA polymerase, which operates exclusively in the 5′ → 3′ direction. This directional activity allows for the continuous synthesis of the leading strand, while the lagging strand is formed in segments known as Okazaki fragments.

Hence, the correct answer is option 4) The DNA dependent DNA polymerase catalyses polymerization in 5' to 3' direction.

Zoology

Q3. Given below are two statements:

Statement I: The presence or absence of hymen is not a reliable indicator of virginity.

Statement II: The hymen is torn during the first coitus only.

In the light of the above statements, choose the correct answer from the options given below :

Options:

1. Both Statement I and Statement II are true

2. Both Statement I and Statement II are false

3. Statement I is true but Statement II is false

4. Statement I is false but Statement II is true

Difficulty: Medium

Explanation:

The presence or absence of a hymen is not a reliable indicator of virginity because the hymen can also be broken by a sudden jolt, insertion of a vaginal tampon,
active participation in some sports and in some women the hymen persists even after coitus.

Hence, the correct answer is option 3) Statement I is true but Statement II is false.

Q4. Match List I with List II:

Choose the correct answer from the options given below:

Options:

1. A-II, B-I, C-III, D-IV

2. A-IV, B-III, C-I, D-II

3. A-III, B-IV, C-I, D-II

4. A-II, B-I, C-IV, D-III

Difficulty: Medium

Explanation:

A. Unicellular glandular epithelium (III) Goblet cells of the alimentary canal
B. Compound epithelium (IV) Lines the moist surface of the buccal cavity
C. Multicellular glandular epithelium (I) Salivary glands
D. Endocrine glandular epithelium (II) Pancreas

Goblet cells are single-celled glands that secrete mucus, aiding in lubrication and protection. Compound epithelium protects against mechanical and chemical stress in areas like the buccal cavity. These glands are made up of multiple cells working together to produce and secrete saliva. The endocrine part of the pancreas (islets of Langerhans) secretes hormones like insulin and glucagon directly into the bloodstream.

Hence, the correct answer is option 3) A-III, B-IV, C-I, D-II.
