botany
Spines are the ends of branches or leafs, that have been modified into rounded, hard structures with sharp ends. They are often also called thorns, which are reduced, sharp pointed stems.
Spines are used by plants to protect themselves from herbivores. Some plants with spines and animals that feed on them, have co-evolved in response to each other, with some plants having very long spines and the animals that feed on those species having long tongues to reach past the spines to feed on the leaves.
