In this blog, we will discuss what assertion reason questions are, how to solve them smartly, why they are important for NEET, and finally provide you with a free chapter-wise PDF of NEET Biology Assertion Reason Questions with solutions.

What Are Assertion Reason Questions?

An Assertion Reason Question is a two-statement question:

Assertion (A): A statement that may be true or false.
Reason (R): A statement that explains why the assertion is true or false.

The student has to check both statements individually and then see if the reason correctly explains the assertion.

Example:

Assertion (A): Photosynthesis occurs only during daytime.
Reason (R): It requires sunlight for the light reaction.

Answer: Both Assertion and Reason are correct, and Reason explains the Assertion.

Why Assertion Reason Questions Are Important in NEET?

Concept Clarity: They test your deep understanding of Biology concepts.
High-Scoring: Usually, these questions are direct and based on NCERT.
Application-Based: They help you apply knowledge instead of just memorizing.
Time-Saving: With practice, you can solve them quickly during the exam.

Every year, NEET examiners include assertion reason questions from Biology, Physics, and Chemistry. However, in Biology, they are more frequent and easier if you prepare well.

Tips to Solve NEET Assertion Reason Questions

Here are some smart tips:

Read both statements carefully – Don’t rush.
Check assertion separately – Is it true or false?
Check reason separately – Is it true or false?
Match the logic – Does the reason correctly explain the assertion?
Avoid assumptions – Stick to NCERT-based facts only.
Practice daily – Regular practice makes solving faster.
