What do we call the edge of a leaf?

The edge of a leaf is referred to as the leaf margin. This is a key anatomical feature of leaves, as it describes not just the boundary but also the specific texture and characteristics along the edge, which can vary significantly between different species of plants. The leaf margin can be smooth (entire), serrated (toothed), or lobed, among other forms, and these variations are important for plant identification and understanding their adaptations to the environment.

In contrast, the leaf tip refers specifically to the apex or the uppermost part of the leaf. The leaf node is the point on the stem where a leaf is attached, which is important in the context of plant structure and growth. Leaf structure generally refers to the overall anatomy of the leaf, including parts like the petiole, blade, and veins, rather than just the edge. Knowing the correct terminology helps enhance understanding of botany and promotes better communication regarding plant characteristics.
