Assertion : CAM plants lack structural compartmentation of leaf as found in $\mathrm{C}_4$ plants. Reason : Stomata of CAM plants are open during the day.
  1. If both assertion and reason are true and reason is the correct explanation of assertion.
  2. If both assertion and reason are true but reason is not the correct explanation of assertion.
  3. If assertion is true but reason is false.
  4. If both assertion and reason are false.

Solution

CAM plants do not exhibit the structural compartmentation as shown by $\mathrm{C}_4$ plants which exhibit kranz anatomy. CAM plants fix $\mathrm{CO}_2$ at night because their stomata are open at night and remain closed during the day.
