What is the role of bulliform cells in grass leaves?

What is the role of bulliform cells in grass leaves?
  1. They are responsible for photosynthesis
  2. They help in prevention of water loss and leaf curling
  3. They are responsible for the parallel venation in monocot leaves
  4. They are responsible for the reticulate venation in dicot leaves

Solution

Bulliform cells in grass leaves absorb water and when turgid, they expand to expose the leaf surface, and when they are flaccid due to water stress, they curl the leaves inwards to minimise water loss.
