Why does a rose plant have thorns?

Answer 1

No, not on the roses but on their pinesues. So that nothing can eat them. It is a defense mechanism. If an animal bites into a rose, and gets a mouthful of thorns, they won't want to eat it anymore.

Answer 2

Roses have thorns to protect against predators. If a plant is covered in sharp thorns it's hard for large herbivores/omnivores (deer for example) to eat the stems, leaves, flowers, and fruit. Small plant eaters, like aphids, can still eat the plant parts very easily, though.

Answer 3

Thorns on a rose plant serve as a defense mechanism against herbivores or pests, deterring them from consuming the plant. Thorns help protect the plant's delicate flowers and leaves by making it difficult for animals to reach them.
