Question

When they are flaccid due to water stress, they make the leaves curl inwards to minimize the water loss

Answer 1

Explanation:

Bulliform cells are thin-walled cells present in the epidermis of monocots, like grasses.

When the bulliform cells absorb water, they become turgid and the leaf surface is exposed.

When they are flaccid due to water stress, they make the leaves curl inwards to minimise water loss.
