In addition to making food for the plants, leaves can be modified to following structures in some plants:
1. Tendrils: In plants such as Gloriosa, leaves are modified into tendrils. These tendrils have the ability to coil across objects and provide support to the plants.
2. Spines: In certain desert plants such as cactus, the leaves are modified into spines. This modification allows cactus to minimise water loss and it also protects the plant from grazing animals.
