Question

Bulliform cells are responsible for

• A. Inward curling of leaves in monocots
• B. Protecting the plant from salt stress
• C. Increased photosynthesis in monocots
• D. Providing large spaces for storage of sugars

Answer 1

The Correct Option is A

Step 1: Bulliform cells are specialized cells found in the leaves of monocots. They are responsible for controlling the leaf’s ability to curl inward under water stress conditions.

Step 2: When the plant experiences water stress or dehydration, bulliform cells lose turgor pressure and cause the leaves to curl inward. This helps reduce the leaf’s surface area exposed to the sun, minimizing water loss through transpiration.

Thus, bulliform cells are responsible for the inward curling of leaves in monocots, especially in response to water stress.
