What is a smooth or a toothed leaf?

A smooth leaf, often referred to as a entire or entire margin leaf, has edges that are even and without any indentations or teeth. In contrast, a toothed leaf features serrated edges with small projections or "teeth" along the margin. These characteristics can help in the identification of plant species and may influence how the leaf interacts with its environment, such as in water drainage or pest resistance. The type of leaf margin can also impact the leaf's overall function and adaptation.
