the gas is CO2
That's what they do.
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.

A gas that plays an important role in the weather is Water Vapor because itaffects the weatheris the form of gas H2O (G).
The circuit controlling the igniter thinks gas is flowing through the valve and the spark is trying to ignite the gas. Close the gas input valve and call your gas stove service person.
Through the stomata carbon dioxide diffuses into the plant and oxygen and water vapor diffuse out of the plant. Guard cells control the opening and closing of the stomata. Used in arid climates to control water loss for instance.
Guard cells are on the surface of plant leaves and surround each stomata (small pores all over the leaf surface). Stomata control the release of gases, including water vapor. During a drought plants occasionally look droopy but still alive, the plant looks wilted because its guard cells are preventing loss of moisture from the stoma (plural of stomata). When defining stomata, it is made of two parts: the pore (opening) itself, and the (2) guard cells around it.

Guard cells play a crucial role in regulating transpiration and preventing wilting in plants. They control the opening and closing of stomata, small pores on the surface of leaves. When the guard cells uptake water, they swell and the stomata open, allowing gas exchange for photosynthesis and transpiration. Conversely, when guard cells lose water, they shrink and close the stomata, preventing excessive water loss and wilting.

Gases enter and exit a leaf through stomata. These are openings in the epidermis which are regulated by guard cells. Guard cells decide which gases can go in and out. The gas that goes in is carbon dioxide and the gas that goes out it oxygen.
