Question

Two points in which photosynthesis and respiration in plants are opposite to each other.

(a) In photosynthesis, $C{O}_2$ is consumed while in respiration $C{O}_2$ is given out.
(b) The photosynthesis is a catabolic process while respiration is an anabolic process.

Which is true?

• A. Both (a) and (b) are True
• B. Neither (a) nor (b) are True
• C. (a) is True and (b) is False
• D. (a) is False and (b) is True

Answer 1

The correct option is C

(a) is True and (b) is False

(a) is True and (b) is False.

In photosynthesis, $C{O}_2$ is consumed while in respiration $C{O}_2$ is given out. And photosynthesis is an anabolic process while respiration is a catabolic process. Anabolic processes are those where complex molecules are built from simple molecules. It is also called as constructive metabolism. In photosynthesis, glucose is generated from simple molecules. Catabolism is a breakdown process, also known as destructive metabolism. In respiration, glucose is broken down to get energy.
