It absorbs water and forms an arc, the outer layer thins as water is absorbed.
The guard cells are specialized cells that control the opening and closing of the stomata in plant leaves. They can change shape to regulate the exchange of gases and water vapor between the leaf and the surrounding environment.
Stomata open and close in response to changes in turgor pressure within the guard cells. When guard cells take up water, they become turgid and the stomata open to allow gas exchange. Conversely, when guard cells lose water, they become flaccid and the stomata close to prevent water loss.
The specialized cells that control the aperture of the stomata are called guard cells. These cells change shape to open and close the pore of the stomata, thus regulating gas exchange and transpiration in plant leaves.

Guard cells are the specialized cells that monitor and regulate the size of stomata in plant leaves. They control the opening and closing of stomata to regulate gas exchange and water loss in the plant.
The guard cells are specialized cells that control the opening and closing of the stomata in plant leaves. They can change shape to regulate the exchange of gases and water vapor between the leaf and the surrounding environment.
Guard Cells surround the stomata, and enable it to open or shut.
The stomata are the pores and the guard cells control the opening and closing of these pores.
The guard cells.
The guard cells open and close the stomata as needed.
Stomata open and close in response to changes in turgor pressure within the guard cells. When guard cells take up water, they become turgid and the stomata open to allow gas exchange. Conversely, when guard cells lose water, they become flaccid and the stomata close to prevent water loss.
The specialized cells that control the aperture of the stomata are called guard cells. These cells change shape to open and close the pore of the stomata, thus regulating gas exchange and transpiration in plant leaves.
Guard cells form the stomata. They can open and close to regulate the exchange of gases such as oxygen and carbon dioxide, as well as control water loss in plants.
guard cells
Guard cells. They are bean-shaped and this allows for the opening and closing of stomata.
Guard cells are the specialized cells that monitor and regulate the size of stomata in plant leaves. They control the opening and closing of stomata to regulate gas exchange and water loss in the plant.
The stoma is "turgor operated valve". The opening and closing of stoma is regulated by the turgidity of guard cells. The stomata are open when the guard cells are turgid. On losing turgidity in guard cells, the stomata closes.
