Leaves exhibit various patterns that can be categorized based on their shapes, sizes, and arrangements. Common leaf shapes include oval, lobed, and needle-like, while arrangements can be alternate, opposite, or whorled. These patterns help identify different plant species and adapt to their environments. Additionally, the surface of leaves often displays unique patterns, such as veins that transport nutrients and water. The arrangement of these veins can be pinnate, palmate, or parallel. These patterns not only contribute to the leaf's functionality but also enhance its aesthetic appeal in nature.
