Vedclass · Answer

(B) Desert plants are adapted to survive in water-scarce environments. $1$. They possess a thick cuticle on their leaf surfaces to minimize water loss through transpiration. $2$. They follow the $CAM$ (Crassulacean Acid Metabolism) pathway for photosynthesis,which allows them to fix $CO_2$ at night. $3$. Consequently,their stomata remain closed during the day to prevent water loss and open at night to take in $CO_2$. $4$. Stomata in desert plants are typically 'sunken' (sunken stomata) to reduce water loss,not located on the surface of the epidermis. Therefore,the statement that stomata are located on the epidermis is incorrect.

Which of the following characteristics does $NOT$ apply to desert plants?
