Question

What are bulliform cells? what are their functions?

Answer 1

Bulliform cells:

1. Bulliform cells, also known as motor cells, are huge, bubble-shaped epidermal cells found on the top surface of leaves in groups of multiple monocots.
2. These cells are found on the top or adaxial leaf surface.
3. They are usually found at the midvein part of the leaf.
4. These are large, white, and colorless cells.

Functions of bulliform cells:

1. In times of scarcity of water, the leaves curl up in order to reduce the evaporation process.
2. During times of stress, bulliform cells assist in the rolling of leaves to avoid water loss through transpiration.
3. As a result, they govern the process of transpiration.
4. They also unfold the leaves when the conditions are right.
