      Cacti are equipped with many adaptations that suit them for the desert life. Instead of leaves, from which water escapes
      easily, this magnificent plant has spines, which greatly narrow down
      water evaporation. The spines also protect the cactus from hungry
      predators such as birds. A cactus has short roots, which also minimize
      evaporation. A cactus is a vascular plant, meaning it can support
      itself while growing to amazing heights. The saguaro cactus can grow
      unto an astonishing 45ft. Probably the most amazing fact about this
      plant is that even in its harsh climate some cacti can survive over 200
      years! These adaptations allow certain cacti to survive 3 years without
      water; a human can barely survive 4 days.
