Leaves are aerial plant parts that play a vital role in photosynthesis.
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 one another. Leaves present on the shaded side of a plant have different sizes and colours in comparison to the leaves that receive direct sunlight.
In conclusion, we can say that no two leaves are identical. All leaves are unique.
