• 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.
