Question: 94. Bulliform cells are responsible for
(1) Inward curling of leaves in monocots.
(2) Protecting the plant from salt stress.
(3) Increased photosynthesis in monocots.
(4) Providing large spaces for storage of sugars.
Answer: Option (1)
Explanation:
Bulliform cells are large, thin-walled cells present in the upper epidermis of monocot leaves,
especially grasses.
These cells help in rolling and unrolling of leaves in response to water availability.
During water stress, bulliform cells lose turgidity and cause inward curling of the leaf.
This inward curling reduces the surface area exposed to sunlight and helps in reducing water loss through transpiration.
Hence, bulliform cells are responsible for inward curling of leaves in monocots.
