Most xerophytic plants have a thick waxy cuticle on their stems and leaves if they have them. The waxy cuticle also helps prevent evaporation of water by being shiny, and the shininess helps reflect the sunlight, which reduces evaporation as sunlight can cause water to evaporate.

About Homeostasis
Homeostasis maintains a stable internal environment through the kidney and urinary system, thermoregulation and excretion. The kidney topics include filtration, selective reabsorption, urine formation and water balance, while thermoregulation involves sweating, vasodilation, vasoconstriction and hormonal control; excretion is different from egestion, which removes undigested food.
