Why do leaves vary in shape?

Can you tell the difference between the leaf of a mango tree and that of a jack fruit tree by examining them? The shape and appearance of leaves varies from tree to tree. Some leaves are rough and jagged, while some others are smooth and soft. The blades of leaves may be simple and undivided or divided in multiple counts.

The leaves of a drumstick plant are very small. They are arranged in a single vein separately. There are other patterns of leaves as well. They may appear alternatively or in pairs. Leaves arranged in pairs may face the same way, or are at right angles to each other.

All trees have leaves; however, their uniqueness gives identity to the tree and adds beauty to nature.
