Stomata are small pores on the surface of plant leaves that allow for gas exchange, such as the intake of carbon dioxide and the release of oxygen and water vapor. Guard cells surround each stoma and regulate its opening and closing to control gas exchange and prevent excessive water loss through transpiration.
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 in response to environmental cues such as light intensity, carbon dioxide levels, and internal plant signals like hormones. When guard cells surrounding the stomatal pore take up water and become turgid, they bow outwards, causing the stomata to open. Conversely, loss of water causes the guard cells to become flaccid, leading to stomatal closure.
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.

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.
Guard cells are specialized cells in plant leaves that control the opening and closing of stomata, which are small pores that regulate gas exchange and water loss. By changing their shape and turgor pressure, guard cells can regulate the size of the stomatal pore to balance photosynthesis with water conservation in response to environmental conditions.
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.
