Transpiration occurs at the stoma.
Passing outwards through the stoma are water vapour, and oxygen. Passing inwards is mainly carbon dioxide.
Stoma (plural stomata), they are the pores used for gas exchange.
Transpiration.
A stoma is surrounded by a pair of guard cells, which regulate its opening and closing. Therefore, each stoma typically has two guard cells. These cells play a crucial role in controlling gas exchange and water loss in plants.
stomata =Specialized passages through the cuticle that enable plants to exchange gases.

The cells that surround the stoma are called guard cells. These specialized cells are responsible for regulating the opening and closing of the stoma, which facilitates gas exchange in plants. By changing their shape in response to environmental conditions, guard cells control water loss and the intake of carbon dioxide for photosynthesis.
