Motor cells are:-


a) Present in xylem to transport water during transpiration.
b) Thin walled, large empty cells on the upper epidermis of leaves.
c) Also help in the formation of trichomes.
d) Helper cells associated with guard cells.

Kindly answer sir/mam.

Dear student,
Please find below the solution to the asked query

The correct option of b).
Motor cells also called bulliform cells are the large thin-walled, empty cells that occur in the epidermis of leaves of many grasses. During dry weather, these cells regulate water loss by changing turgidity that causes rolling and unrolling of the leaves. The rolled leaves offer less exposure to sun that reduces rate of stomatal transpiration and hence excess water loss.

Hope this information will clear your doubts about the motor cells.
