In the following question, a statement of assertion is following by a statement of reason. Mark the correct choice as:
Assertion: CAM plants lack structural compartmentation of a leaf as found in C4 plants.
Reason: Stomata of CAM plants are open during the day.
If assertion is true but reason is false.
CAM plants do not exhibit the structural compartmentation as shown by C4 plants which exhibit kranz anatomy. CAM plants fix CO2 at night because their stomata are open at night and remain closed during the day.
