Question

Assertion (A): Collenchyma provides mechanical strength and flexibility.

Reason (R): It has thickened walls with lignin.

विकल्प

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

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

• A is true but R is false.

• A is false but R is true.

Answer 1

A is true but R is false.

Explanation:

Collenchyma provides support and flexibility, so A is true. Its cell walls are unevenly thickened with cellulose and pectin, not lignin; therefore, R is false.
