Question

During water stress, the bulliform cells:
(a) Become turgid
(b) Become flaccid
(c) Make the leaves curl inwards

• A. only (a)
• B. only (b)
• C. (a) and (b)
• D. (b) and (c)

Answer 1

The correct option is D (b) and (c)

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.
