Detailed explanation-1: -The guard cells are structurally adapted to their function by; Adaptations of the guard cell to its function of opening and closing of stomata in plants.-The wall of the guard cell is differentially thickened with the inner membrane to open the stoma when turgid.

Detailed explanation-2: -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. This helps to stop the plant from wilting .

Detailed explanation-3: -Guard cells are kidney shaped cells that surrounds the stomata. They control the opening and closing of the stomata. When the plant has an excess of water, the guard cells swell and create an opening for the exchange of gases.

Detailed explanation-4: -The guard cells surround each stoma for their protection. They are the cells that regulate the rate of transpiration by opening and closing of stomata. The guard cells swells up and open the stomata for the exchange of gases when the plant has an excess of water.

Detailed explanation-5: -Guard cells are located in the leaf epidermis and pairs of guard cells surround and form stomatal pores, which regulate CO2 influx from the atmosphere into the leaves for photosynthetic carbon fixation. Stomatal guard cells also regulate water loss of plants via transpiration to the atmosphere.
