Assertion (A): All the parts of a plant respire all the time, whether it is day or night.
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.
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R is not the correct explanation of A.
- A is true but R is false.
- A is false but R is true.

Answer
A is true but R is false.
Reason — A is true as all parts of a plant respire continuously, both day and night, to produce energy.
R is false because all parts of a plant respire, not just leaves. Stems respire through lenticels, while roots respire through their general surface/root hairs.
Therefore, A is true but R is false is the correct option.
