Adaption of a plant: Cactus

The Cactus is a plant that has learned to adapt to its environment in the desert. Cactus have adapted to the environment where there is no water for months by teaching itself to spout at any moment when the rain falls, bloom quickly, ripen their seeds in a few days, then die. The cactus also has a thick waxy layer on the outside of its stems and leaves that help it retain water and protect it from the sun. Most cactus and other plants in the desert have developed roots that grow up

 to 80ft. long that allow them to reach the water well below the desert floor
