Leaves of various trees are different from each other in their shape, size, edges and outlook. Some leaves are round, long or triangular. Many plants have small or big leaves. Even colours of leaves are different. Some are light green and some dark green. Some are even yellow, red and purple. There is one which is green but has white patches on it. Apart from this, margins of leaves are different from each other. Some have straight margins and some uneven. Some of the margins look like a saw.
