Assertion (A): Respiration is a catabolic process which produces energy in the form of ATP.
Reason (R): Respiration is the process in which glucose is broken down in a series of chemical steps to produce energy.
- 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
Both A and R are true and R is the correct explanation of A.
Reason — A is true as respiration is a catabolic process.
R is true as it breaks down glucose to release energy in form of ATP.
Therefore, Both A and R are true and R is the correct explanation of A is the correct option.

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.
