AI overview
A spinose structure is a sharp, pointed outgrowth on a plant—such as a modified shoot, leaf, root, or extension of the outer plant tissue—that serves as an adaptation for protection or other survival purposes. These spine-like structures matter because they help plants defend themselves against herbivores and can also aid in water conservation or other ecological functions.
