Vedclass · Answer

(A) Bulliform cells,also known as motor cells,are large,bubble-shaped epidermal cells found in groups on the upper surface of the leaves of many monocots,such as grasses.These cells are empty and colorless because they lack chloroplasts.When these cells absorb water and become turgid,the leaf surface expands.When they lose water due to stress (like drought),they become flaccid,causing the leaf to curl inward to minimize water loss through transpiration.
