Question

Assertion (A): Photosynthesis occurs in all parts of a green plant.

Reason (R): Chlorophyll is the green pigment which traps solar energy during daytime.

Options

• 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 False and R is True.

Explanation:

A is false. Photosynthesis takes place only in the parts of a plant that contain chlorophyll, mainly the green leaves. Non-green parts do not have chlorophyll, so they cannot carry out photosynthesis. R is true. Chlorophyll is necessary for absorbing sunlight, which provides the energy needed for photosynthesis.
