Question

Kidney shaped cells that surround the stomata are called guard cells. True or false?

• A. True
• B. False

Answer 1

The correct option is A

True

Guard cells surround each stoma. They help regulate the rate of transpiration by opening and closing the stomata. When the guard cells are turgid or swollen, the stomatal opening is large and transpiration can occur and when the guard cells have lost water or flaccid, the stomatal opening closes thereby pausing transpiration.
