Detailed explanation-1: -Stomatal guard cells play a key role in the ability of plants to survive on dry land, because their movements regulate the exchange of gases and water vapor between the external environment and the interior of the plant.
Detailed explanation-2: -Guard cells are pairs of epidermal cells that control gas diffusion by regulating the opening and closure of stomatal pores.
Detailed explanation-3: -Guard cells are adapted to their function by allowing gas exchange and controlling water loss within the leaf. The size of the stomatal opening is used by the plant to control the rate of transpiration and therefore limit the levels of water loss from the leaf.
Detailed explanation-4: -They aid in the flow of gases between the atmosphere and plants. Guard cells regulate the opening and closing of stomatal holes, which are controlled by the process called osmosis. The entry of water into the stomata makes guard cells swell which leads to the opening of the stomata.
