• A. True
• B. False

Answer 1

The correct option is A True

Stomata:

1. Stomata are the pores present on the epidermis layer of leaves through which the exchange of gases and water loss occurs.
2. Stomatal pores are enclosed by a pair of guard cells that control the opening and closing of stomata.
3. Turgidity of the guard cells regulates the opening and closing of stomata.
4. The outer thick cell walls of the guard cells swell out as the turgidity inside the guard cells increases.
5. This exerts a force on the inner walls of the guard cells, causing them to form a crescent shape and the stomata to open.

The given statement is true.
