Detailed explanation-1: -The opening and closing of stomata are controlled by specialized cells called guard cells. The turgor pressure in the guard cells controls the opening and closing of the guard cells. Stomatal pores open when guard cells enlarge as a result of water absorption and close when guard cells shrink.

Detailed explanation-2: -Two highly specialized cells, the guard cells that surround the stomatal pore, are able to integrate environmental and endogenous signals in order to control the stomatal aperture and thereby the gas exchange.

Detailed explanation-3: -Stomata consist of microscopic pores, each flanked by a pair of guard cells. Guard cells can increase or decrease the size of the pore via changes in their turgor status, hence regulating both CO2 entry into the leaf and transpiration, or the loss of water from the leaf.

Detailed explanation-4: -Stomata and Guard Cells. The role of stomata and guard cells are to control gas exchange and water loss. Stomata allow the evaporation of water. Stomata are small gaps in the leaves that allow water to move through.

Detailed explanation-5: -The opening and closing of stomata depend on the turgor pressure, caused by the osmotic flow of water in the guard cells. When the guard cells are turgid, they expand resulting in the opening of stomata. When the guard cells lose water, they become flaccid leading to stomatal closure.
