Guard cell is an epidermal cell that is also a multisensor hydraulic valve. The guard cells surround the stomatal pore which controls the opening and closing of the stomatal. Due to tugor changes,the guard cells can be triggered by light, temperature, carbon dioxide concentration and hydration of the leaf.
