Question
Bulliform cells are responsible for
Options
A.Increased photosynthesis in monocots.
B.Providing large spaces for storage of sugars.
C.Inward curling of leaves in monocots.
D.Protecting the plant from salt stress.
Solution
Sol. [Key Concept: Bulliform cells and leaf rolling]
Bulliform cells are enlarged epidermal cells on the adaxial surface of grass leaves. When turgid, they help keep the leaf expanded. Loss of turgor during water stress causes inward rolling, reducing the exposed surface and water loss. Hence, option (3).
