NEET 2024, Biology Q10: Anatomy of Dicotyledonous and Monocotyledonous Plants

NEET2024Biology
Q.

Bulliform cells are responsible for:

  1. A

    Increased photosynthesis in monocots

  2. B

    Providing large spaces for storage of sugars

  3. C

    Inward curling of leaves in monocots

  4. D

    Protecting the plant from salt stress

Solution

Bulliform cells are large, empty, colourless epidermal cells found on the upper surface of many monocot leaves (e.g., grasses). When they lose turgor under water stress, the leaf rolls inward, reducing transpiration. This inward curling is their key adaptive function.
