Vedclass · Answer

(B) Spines are modified leaves or branches that serve as a protective mechanism for plants. In many shrubs,especially in environments where herbivory is a significant threat,spines act as a physical defense against browsing animals (mammals). By making the plant difficult to consume,the plant protects its biomass from being eaten. While some modifications like reduced leaf surface area are linked to transpiration,spines in shrubs are primarily evolved for protection against herbivores.
