Guard cell: There are two specialized guard cells. First is gaseous exchange i.e. In plants, a stoma is a tiny pore in the surface of a leaf that is used for gas exchange. The turgor changes in the guard cells are due to entry and exit of water into and out of the guard cells. Vector illustration of a Cross section of a Leaf anatomy Cross Section of a Leaf. About Us. Stomata control a tradeoff for the plant: they allow carbon dioxide in, but they also let precious water escape. They also facilitate transpiration, which helps the absorption of water from the soil and the transport of water through the xylem.The size of the stomata is controlled by a pair of guard cells. 2.3k VIEWS. 4:38 1.4k LIKES.
