Do leaves have teeth?
The zigzag edges of leaves, so-called leaf teeth, are important for making the characteristic shapes of each leaf. Many leaves have small zigzags called leaf teeth on their margin. Examples of plants that contain leaf teeth include cherry blossoms, maples, dandelions and shiso that are used with many Japanese dishes.
