They waxy cuticle keeps water inside the leaf cells. Tis water is then used for photosynthesis. ... Suggest a way in which the stoma and guard cells arrangement might work to control the amount of water that is leaving the leaf. The guard cells regulate the opening and closing of the stomata.
The stomata is the opening in the leaf that regulates what enters and exits. These holes go through the waxy cuticle, the covering of the leaf. The cuticle prevents things from entering and exiting the leaf. The stomata regulates the amount that DOES go in and out by opening and closing.
