Adaption of a Plant

This is a picture of a cactus. Cacti represent an example of an adaption of a plant. Plants adapt to their environments just as animals would. Plants that live in extreme environments, such as the desert or the Artic, must learn to store nutrients and water for times when they are not available. Cacti are a good example of a plant that has adapted over time because they store water in their roots. Another example of how they have changed over time, is by growing sharp, pointy, and sometimes poisonous spurs on their bodies to protect themselves from humans or animals. These strategies are mainly used in order to keep birds from landing on them and stealing their stored water.
