NEET 2026, Biology Q9: Anatomy of Dicotyledonous and Monocotyledonous Plants

NEET2026Biology
Q.

The main function of bulliform cells in grasses is :

  1. A

    to make the leaf impermeable to fungal spores.

  2. B

    to transport water.

  3. C

    to perform photosynthesis.

  4. D

    to minimize water loss during water stress.

Solution

Bulliform cells are large, colourless, empty epidermal cells in grasses. Under water-deficient conditions, they lose turgor and become flaccid, causing the leaf to curl inward. This curling reduces the exposed surface area and limits transpirational water loss.
