Leaves are plant parts that play a vital role in photosynthesis.
In spite of performing the same function, all leaves are unique.
The shape of a leaf varies between plant species. Leaves can be broad, flat, and needle-shaped. Variation in shapes arises as a result of adaption to different climatic conditions.
The leaves of the same plant can also be different from each other. Leaves present on the shaded side of a plant have different sizes and colors in comparison to the leaves that receive direct sunlight.
