They shut because with the stomata open it is too drafty and the plant can't get to sleep.
To stop water loss from the plant. In the day light photosynthesis is taking place and carbon dioxide needs to be admitted into the stomata for this process. At night, no light, so plants, who lose water all day long, as it is replaced by the roots, shut the no longer needed stomata to conserve water.
Stomata are shut at night to conserve water. When there is no light, plants cannot fix carbon dioxide. Stomata are usually open to allow entrance of carbon dioxide. A side effect is that water is lost from the leaves.There is an exception to this, however. CAM plants such as cacti and succulents open the stomata at night, store carbon dioxide as acids, and close them during the day to prevent dessication from harsh desert conditions.
Stomata do not occur - during the night or day. Stomata are physical features of leaves: they are there from when the leaf is created to when it dies.
probably means it is shut. since carbon dioxide goes through the stomata and is necessary for photosynthesis then if there is a low amount of it in the leaf then the stomata must be shut
Hey, I figured it out when there is a low concentration of CO2 in the leaf the Stomata opens.
Guard Cells surround the stomata, and enable it to open or shut.
Closing stomata at night helps conserve water by reducing transpiration when there is no sunlight for photosynthesis. It also prevents the loss of stored sugars and other nutrients through transpiration during the night. Additionally, closing stomata at night can reduce the risk of herbivory or pathogen entry when the plant is less active.
At night, the leaves of C3 plants close their stomata and wait until the sunlight. For CAM plants, this is when the plants open their stomata and allow the carbon dioxide to come in.
It is through a opening called stomata

Slows water loss by opening stomata only at night
