Vedclass · Answer

(A) In isobilateral leaves,the upper epidermis contains specialized cells known as bulliform or motor cells.These cells are large,empty,and colorless,and they are capable of storing water.When the plant has sufficient water,these cells become turgid,which helps in the unrolling of the leaf.Conversely,during water stress,these cells lose water and become flaccid,causing the leaf to roll inward to minimize water loss.Therefore,both the Assertion and the Reason are correct,and the Reason correctly explains why bulliform cells are involved in the movement of the leaf.

Assertion: Bulliform cells are useful in the unrolling of leaf.
Reason: Bulliform cells store water.
