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: -Upon the incoming of water inside the guard cells, they swell up to become like a curved banana surface, due to which the stomatal pore opens up. When the guard cells lose water, they become flaccid and straight and thus, close the stomatal aperture. Guard cells and stomata regulates the respiration process in plants.

Detailed explanation-3: -The opening and closing of stomata are controlled by changes in the shape of the two guard cells that surround each pore.

Detailed explanation-4: -Final answer: The opening and closing of the stomatal pore depend upon water in guard cells.

Detailed explanation-5: -Guard cells are pairs of epidermal cells that control gas diffusion by regulating the opening and closure of stomatal pores.
