Question

Assertion (A): Plants absorb water mostly by roots.

Reason (R): Root cap region participates actively in water absorption.

विकल्प

• Both A and R are true and R is the correct explanation of A.

• Both A and R are true but R is not the correct explanation of A.

• A is true but R is false.

• A is false but R is true.

Answer 1

A is true but R is false.

Explanation:

The assertion is true because terrestrial plants absorb the vast majority of their water and mineral requirements from the soil through their root systems. However, the reason is false because the root cap region does not participate in water absorption; its sole purpose is to protect the delicate growing tip of the root from mechanical damage. Active absorption of water is instead carried out by the root hair zone, which is located just behind the region of elongation.
