Stomatal transpiration takes place during day time in the following plants EXCEPT________.
Options
- ALotus
- BMango
- CGrass
- DCactus
Correct answer
D. Cactus
Step-by-step solution
Cactus is a xerophytic plant that exhibits Crassulacean Acid Metabolism (CAM).
In CAM plants, the stomata remain closed during the daytime to prevent excessive water loss through transpiration.
The stomata open during the night (scotoactive stomata) to take in carbon dioxide.
Therefore, stomatal transpiration does not take place during the daytime in Cactus, whereas it occurs during the daytime in Lotus, Mango, and Grass.
