The two guard cells one either side contract to open and close stoma.
It's actually the guard cells. Water vapor does go through it, though.
2 guard cells
Guard cells are what surround stomata.
Stoma, they take in Carbon dioxide and let out oxygen
Guard cells change shape to open and close stomata. When they are flaccid, the stoma is closed. When they are full of water and firm, the stoma is open. There are 2 guard cells controlling a stoma. Water enters guard cells by osmosis and they change shape.
the function of guard cells are that they control the opening and closing of the stoma
There are a large number of tiny pores called stomata on the surface of leaves of plants (The singular of stomata is stoma).Each stomatal pore (or stoma) is surrounded by a pair of guard cells .The opening & closing of stomatal pores are controlled by the guard cells.

the function of guard cells are that they control the opening and closing of the stoma
The stoma opens and closes to allow gas exchange. The Guard cells are located around the stoma and regulate the opening and closing of the stoma.

Guard cells make up the stoma

2 guard cells
control the size of the openings called stoma the stoma allow gases such as carbon dioxide and oxygen to move into and out of the leaf
