Thorns
Sharp points on a plant, stem, or branch are often referred to as thorns or spines. Thorns are modified branches that have evolved to deter herbivores and protect the plant from being eaten. These structures can vary in size and shape, serving as a defense mechanism to enhance the plant's survival. Examples of plants with thorns include roses and hawthorn trees.
