Phyllotaxy refers to the arrangement of leaves on a plant stem. This pattern is crucial for maximizing sunlight exposure and minimizing shading of lower leaves. Common types of phyllotaxy include alternate, opposite, and whorled arrangements, each serving different ecological functions. The study of phyllotaxy helps botanists understand plant growth and development. It can also influence how plants compete for resources and adapt to their environments. By analyzing these patterns, researchers can gain insights into the evolutionary strategies of various plant species.
