What is the function of stomata in leaves?

Middle School


The main function of Stomata in leaves is:

  • Taking in oxygen is very important because it allows your cells to do things, like make energy from the food you eat. Plants 'breathe' too, but they do it through tiny openings in leaves called stomata (singular: stoma). Stomata open and close to allow the intake of carbon dioxide and the release of oxygen.



  • Exchange of the gases is the primary and main function of stomata. The opening and closing of stomata is controlled by specialised cells called guard cells. Stomata helps the plants to take carbon dioxide in and leave oxygen out as a waste product.
