    What are the different modifications of leaves?

    In many plants, their leaves are modified to perform some special functions other than photosynthesis and transpiration. We learn about some of these modifications.

    Tendrils

    Tendrils are delicate thread-like structures that help in anchoring the weak stemmed plants like climbers. Tendrils are the modification of leaves, stems, or petiole.

    They do not possess a leaf blade but are capable of performing photosynthesis.

    Tendrils

    Thorns

    In plants like cactus, the leaves are modified into spines also called thorns.

    They help in lowering the rate of transpiration to prevent water loss. They also provide protection against the grazing animals.
