What are the functions of bulliform cells in various monocots?
They increase the absorption surface area.
They help in rolling the leaves to reduce transpiration during times of water stress.
They have the myrosinase enzyme present to deter herbivores.
They gather water and mineral nutrients from the soil.
Bulliform cells are inflated bubble-shaped epidermal cells found on the adaxial surface of leaves in many monocots, according to the given text. They are also known as motor cells because they aid in the rolling of the leaves to prevent transpiration during water stress. As a result, option b) They assist in rolling the leaves to prevent transpiration during water stress is the preferred alternative.
Option b is the correct answer.
