guard cells can close stomata

Detailed explanation-1: -A net movement of ions out of the cell causes water efflux and closure of the stomatal pore.
Detailed explanation-2: -Waxy cuticles, trichomes (leaf hairs), sunken stomata, and other leaf adaptations also help reduce transpiration rates by keeping the leaf surface cool or protecting it from air currents that increase evaporation.
Detailed explanation-3: -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-4: -Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata. Light is the main trigger for the opening or closing.
