The correct answer is: If assertion is true but reason is false.
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.
