III. Adaptations for Protection

We’ve already talked about some plant adaptations for protection. Cactus spines certainly deter anyone even thinking about munching on that succulent stem. And a waxy cuticle protects tender plant tissues from drying out. In this section, we’ll look at other ways plants protect themselves.

Some of the most fascinating adaptations are those that help plants protect themselves—remember, they can’t run away from their foes! Again, random mutations yield plants with unique features, both harmful and beneficial. Some mutations lead to characteristics that protect the plant from the particular hazards they face. These individuals survive, and pass their genes on to subsequent generations.
