NEET · Biology · STD 11 - 6. Anatomy flowering plants
The main function of bulliform cells in grasses is :
- A to make the leaf impermeable to fungal spores.
- B to transport water.
- C to perform photosynthesis.
- D to minimize water loss during water stress.
Answer & Solution
Correct Answer
(D) to minimize water loss during water stress.
Step-by-step Solution
Detailed explanation
(D) to minimize water loss during water stress.
Bulliform cells are large, empty, colourless cells present on the adaxial epidermis of grass leaves.
When water is abundant, these cells absorb water, become turgid, and cause the leaf surface to be exposed.
During water stress, they lose turgor pressure and become flaccid, which makes the leaves curl inwards to minimize water loss.
