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.
