Assertion (A): Plants respire only during the daytime when stomata remain open.
Reason (R): Among all the parts of a plant, only the leaves respire because they contain stomata which help in the diffusion of respiratory gases.

Answer
Both A and R are False.
Reason — Plants respire continuously, both day and night, to produce energy. All parts of a plant (leaves, stems, roots) respire, not just leaves. Stems respire via lenticels while roots respire via root hairs.
