The main function of bulliform cells in grasses is :
D. to minimize water loss during water stress.
Bulliform cells are large, empty, colourless cells present on the adaxial epidermis of grass leaves. When water is abundant, these cells absorb water, become turgid, and cause the leaf surface to be exposed. During water stress, they lose turgor pressure and become flaccid, which makes the leaves curl inwards to minimize water loss. Answer: to minimize water loss during water stress.
