The stomata closes duirng the night when there is no light, this is because photosynthesis only takes place during the light and that is when the stoma is open , to let in carbon dioxide for photosynthesis. Otherwise it is closed.

The Guard cells
Stoma
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.
Dark reaction is taken place. It is the light independent reaction
There are two guard cells on each stomate. They can open and close the pathway.

OpenIn day light , they are open, and perform the following three functions1. Transpiration2. Gaseous exchange3. Promotion of ascent of sap
Stomata open due to a decrease in water content inside guard cells, causing them to become turgid and curve outward. This creates an opening for gas exchange. Stomata close when the water content in guard cells increases, causing them to become limp and close the opening to prevent water loss.
