Don't Eat Me!

Insects and other animals can protect themselves from attachers. Did you know that plants have ways to protect themselves too? One way plants protect themselves is with thorns and bark. For example, the thorns on a rosebush make it difficult for animals to eat it. The bark on a tree keeps insects from getting inside. Another way plants protect themselves is with chemicals.
