Question
Assertion : CAM plants lack structural compartmentation of leaf as found in C4 plants.
Reason : Stomata of CAM plants are open during the day.
If both assertion and reason are true and reason is the correct explanation of assertion
If both assertion and reason are true but reason is not the correct explanation of assertion
If assertion is true but reason is false
If both assertion and reason are false
Solution
C.
If assertion is true but reason is false
CAM plants do not exhibit the structural compartmental 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.
