The cooler temperatures, lack of sun, and calmer breezes help cacti retain water. Once the sun rises, the plant goes to work making sugars. Cacti have also developed succulent tissue, waxy skin, prickly spines, and a specialized root system to take every advantage in their harsh ecosystems.A cactus has special adaptations in its roots, leaves as well as stems that enable it to thrive in desert environments. These adaptations include: Leaves are reduced to spines to reduce water loss through transpiration. Wide and deep roots absorb rainwater on the surface and reach the underground deep water.Because it has no leaves, it doesn’t give up its water through evaporation as easily as other plants. Its stems are thick with a lot of room for storing water, and with a protective covering that keeps the stored water inside. Some cactus species can go for two years without water.
