What describes basal leaf arrangement?

Basal leaf arrangement refers specifically to leaves that are positioned at the base of a plant, which can often form a rosette configuration. This arrangement allows the plant to maximize its exposure to sunlight while minimizing shading from other leaves. In many species, the basal leaves are larger than those that grow higher on the stem, adapting to their role in photosynthesis. The rosette formation is particularly beneficial in environments where conditions may hinder growth, as it allows the plant to gather more light and nutrients efficiently.

In contrast, the other descriptions refer to different types of leaf arrangements. Leaves at various heights on the stem describe an alternate arrangement, while one leaf per node alternating sides refers to an alternate leaf arrangement as well. Finally, two leaves per node situated opposite each other characterizes an opposite leaf arrangement. Each of these arrangements serves different biological functions and adaptations, underlining the diversity of plant morphology.
