Question: Explain how opening and closing of stomata occurs during transpiration?

The opening and closing of stomata occurs during transpiration in response to changes in the plant's water balance. When a plant has sufficient water, guard cells surrounding the stomata swell with water, causing them to curve and open the pore. This allows for the exchange of gases between the plant and the surrounding atmosphere, as well as the release of water vapor during transpiration. However, when water is limited, the guard cells lose their turgor pressure and become flaccid, causing the pore to close and reduce water loss through transpiration. The opening and closing of stomata is controlled by a combination of environmental and internal signals, including light, temperature, humidity, and hormone levels. By regulating the opening and closing of stomata, plants are able to balance their need for carbon dioxide uptake for photosynthesis with the need to conserve water.
