Updated On: May 3, 2026
- To make leaf impermeable
- To perform photosynthesis
- To minimize water loss
- To transport water
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Bulliform cells are large, bubble-shaped epidermal cells that occur in groups on the upper surface of the leaves of many grasses.
• When these cells absorb water and are turgid, the leaf surface is exposed (open).
• When they lose water due to water stress, they become flaccid and cause the leaves to curl inwards to minimize water loss by reducing the exposed surface area.
