Ques 1: Which of the following is the correct unit of productivity in an ecosystem?

A. (KCal m⁻²) yr⁻¹

B. gm⁻²

C. KCal m⁻²

D. KCal m⁻³

Correct Answer: A

Explanation:

Productivity is measured as the rate of energy production per unit area per unit time, hence expressed as KCal m⁻² yr⁻¹.

Ques 2: The first occurrence of menstruation in females is known as:

A. Ovulation

B. Menopause

C. Menarche

D. Diapause

Correct Answer: C

Explanation:

Menarche marks the beginning of the menstrual cycle in females, indicating reproductive maturity.

Ques 3: Genes R and Y assort independently. If RRYY produces round yellow seeds and rryy produces wrinkled green seeds, what is the phenotypic ratio in the F₂ generation?

A. 9:7

B. 1:2:1

C. 3:1

D. 9:3:3:1

Correct Answer: D

Explanation:

This is a classic dihybrid cross showing independent assortment, resulting in a 9:3:3:1 phenotypic ratio.

Ques 4: What is the main function of spindle fibres during mitosis?

A. Regulate cell growth

B. Separate chromosomes

C. Synthesise DNA

D. Repair DNA

Correct Answer: B

Explanation:

Spindle fibres attach to centromeres and pull sister chromatids apart during cell division.

Ques 5: How many meiotic and mitotic divisions are required to form a mature female gametophyte from a megaspore mother cell in angiosperms?

A. No meiosis and 2 mitosis

B. 2 meiosis and 3 mitosis

C. 1 meiosis and 2 mitosis

D. 1 meiosis and 3 mitosis

Correct Answer: D

Explanation:

One meiosis produces four megaspores, followed by three mitotic divisions to form the embryo sac.

Ques 6: Which of the following statements about antibody structure is NOT correct?

A. Constant regions are at C-terminal

B. Two heavy and two light chains are present

C. Chains are linked by disulfide bonds

D. Antigen binding site is at C-terminal

Correct Answer: D

Explanation:

The antigen-binding site is located at the variable (N-terminal) region, not the C-terminal.

To make your preparation for the NEET exam more efficient, we have prepared a PDF that contains the most important questions from the past few years, i.e., from 2023 to 2025. This will make your preparation efficient, help in revising the key concepts, and other relevant information while preparing for the NEET 2026 exams.

Why NEET Biology Previous Year Questions Are Important?

Studying NEET Biology PYQs and their solutions has a number of advantages over simply studying for your exams through regular means:

1. Understanding NEET Exam Pattern

PYQs will help you understand how questions are framed and how difficult a question can get in an actual exam.

• Familiarise yourself with types of questions asked (Statement-based, Match the following, etc.)

• Get a fair idea of the importance of various chapters

• Get more confident for your actual exam

2. Revisiting NEET Repeated Chapters

You will notice that concepts from units such as Genetics, Human Physiology, Ecology, and Plant Physiology are repeatedly asked in NEET.

• Easily identify frequently asked chapters

• Focus more on the important NEET Biology chapters

• Save your time by avoiding chapters you know aren’t important

3. Improving NCERT Concepts

Most of your NEET Biology questions will come from the NCERT. So, it will help you improve your concepts by revising important lines.

• Revise important NCERT statements and diagrams

• Improve your concepts

• Relate your questions to the NCERT

4. Improving Accuracy and Speed

Studying through PYQs will improve your accuracy and speed, helping you manage your time better for your actual exam.

• Answer your questions quickly

• Avoid negative markings

How to Use NEET Biology Important PYQs Effectively?

To score the highest in NEET Biology, you should follow these strategies:

1. Solve PYQs chapter-wise after completing the NCERT

• You should start practising NEET previous year questions only after completing a chapter from the NCERT book.

• This way, you can directly apply the concepts and get a clear idea of how questions are being framed for a particular topic.

2. Revise incorrect questions and weak topics

• Always analyse your mistakes.

• You should keep a separate book for incorrect questions and revise them regularly to avoid repeating the same mistakes.

3. NCERT diagrams, tables, and examples

• Many questions in the NEET Biology exam are being asked from the diagrams and small points mentioned in the NCERT book.

• You should focus on diagrams, tables, and points mentioned in the book.

4. Practice PYQs multiple times before attempting full-length mock tests

• You should not practice PYQs only once.

• Practice previous year questions multiple times before moving on to mock tests.

5. Use PYQs along with mock tests and revision notes

• Use PYQs along with NEET mock tests to get exam temperament.

• Aspirants should revise their short notes daily to improve speed.

30-Day Strategy to Master NEET Biology Expected Questions From PYQs

If you want to score 320+ or even 340+ in NEET Biology, the last 30 days should be focused on NCERT revision + NEET Biology PYQs with solutions. This plan is designed to help you revise efficiently, improve accuracy, and maximise retention.

Week 1 (Days 1–7): Build Strong NCERT + PYQ Foundation

Focus on completing high-weightage chapters with their PYQs.

• Revise 2-3 chapters every day from the NCERT text (line by line).

• Solve chapter-wise NEET biology previous year questions immediately after revising chapters.

• Highlight important lines in the NCERT text and frequently asked concepts.

• Focus on units like Human Physiology, Genetics, and Ecology.

• Keep a notebook to write down mistakes and tricky questions.

Week 2 (Days 8-14): Intensive PYQ Practice + Concept Clarity

Now, let’s move a step further into deeper practice and weaker areas of understanding.

• Daily practice of mixed PYQs from all chapters (80-100 questions)

• Study each question carefully. The focus here is not only on the correct solution of the question, but also on the concepts behind it.

• Revise the weaker topics from the NCERT again

• Daily practice of NCERT diagrams and tables

Week 3 (Days 15–21): Full-Length Practice + Revision

This is an important part of preparing for the exam.

• Take full-length NEET Biology mock tests regularly

• Revise all short notes and previously answered PYQs

• Focus on frequently repeating NEET Biology questions

• Work on time management and question selection

• Avoid learning new things. Only focus on revising

Week 4 (Days 22–30): Final Revision + PYQ Mastery

The final part of your preparation should be focused on building confidence and maximising your ability to retain things.

• Revise only NCERT, PYQs, and short notes

• Re-solve previously wrong questions

• Focus on high-yield questions and frequently repeated questions

• Take light mock tests

• Keep revising light and easy

• Keep revising relaxed and tension-free

Final Preparation Tips for NEET Biology 2026

• Stick to NCERT and avoid unnecessary resources

• Revise Biology daily to retain factual information

• Practice at least 50-100 NEET Biology MCQs daily, including PYQs

• Analyse mistakes and avoid repeating them

• Focus more on accuracy than attempting too many questions

Consistency and smart practice using important NEET Biology PYQs with solutions can help you achieve a top score.
