Bulliform cells

Vedclass · Answer

(B) The correct answer is Bulliform cells.Bulliform cells are large,bubble-shaped epidermal cells present in the upper epidermis of leaves in many grasses.When water is available,these cells are turgid and keep the leaf blade expanded.During water stress,these cells lose water and become flaccid (lose turgidity).This loss of turgidity causes the leaves to curl inwards,which reduces the surface area exposed to the atmosphere,thereby minimizing water loss through transpiration.
