Question

Assertion (A): Active transport does not occur through a non-living semi-permeable membrane.

Reason (R): Active transport is in a direction opposite to that of diffusion, i.e. from a region of lower concentration to higher concentration.

विकल्प

• A is True and R is False.

• A is False and R is True.

• Both A and R are True.

• Both A and R are False.

Answer 1

A is True and R is False.

Explanation:

A is true. Active transport requires energy and occurs in living cells across membranes. R is true. Active transport moves substances against a concentration gradient and requires energy input.
