Question

Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: CAM plants are present in dry and arid environments.
Reason R: The CAM pathway is adapted to minimize water loss and photorespiration.

In light of the above statements, choose the most appropriate answer from the options given below:

• A. Both A and R are correct and R is the correct explanation of A
• B. Both A and R are correct but R is NOT the correct explanation of A
• C. A is correct but R is not correct
• D. A is not correct but R is correct

Hint:

Key differences in Photosynthetic Pathways:
- C3: No spatial or temporal separation (high photorespiration).
- C4: Spatial separation (Kranz anatomy) between mesophyll and bundle sheath cells.
- CAM: Temporal separation (night vs. day) of carbon fixation.

Answer 1

The Correct Option is A
