Solution
The correct option is D bulliform cells
Bulliform cells are colourless, empty epidermal cells found along the mid vein of the grass leaves. When there is sufficient water, bulliform cells absorb water and become turgid due to which leaves become exposed to sunlight. During water stress, these cells lose water and become flaccid. When they are flaccid, leaf gets curled inward to minimize water loss.
