Vedclass · Answer

(D) Bulliform cells are large,bubble-shaped epidermal cells present in the upper epidermis of grass leaves.These cells are thin-walled and contain a large vacuole.When water is abundant,they become turgid,causing the leaf to unfold.When water is scarce,they lose water and become flaccid,causing the leaf to roll inward to reduce the surface area and minimize transpiration.This reversible change in shape due to changes in turgor pressure is known as turgor movement.
