Adaptation of a plant
The cactus is a well adapted plant. To live in the desert a cactus must adapt to conserve water. The cactus has waxy leaves, long roots, and needles all to adapt to desert climate. Different cacti have adapted in different ways. Some are grayish in color to reflect sunlight and stop losing water. Most have swollen stems for water storage. Some have rolled up leaved to limit the amount of area exposed to the sun, therefore saving water and they are covered in needles to prevent animals from harming the plant. The picture above shows a cactus covered in needles.
