Thorns, prickles and sharp spines help to protect a plant from hungry animals. They may also stop insects boring into the plant. Cows in a meadow will eat grass but not thistles, because they have too many spines. Sometimes seeds are prickly so that they will cling to an animal's fur and SO get spread around.They are carried by the animal to a new patch of ground, brushed off, and fall to the earth where they can start to grow.
