Hint: Depending on the location, climatic conditions plants develop survival mechanisms. These survival mechanisms include modifying their parts to perform additional function. Different parts of the plant like root, stem and leaves undergo modification to perform additional functions.
Complete answer:
Plant has different parts like root, stem and leaves. Each of them has a separate function to perform. In special cases, these structures get modified to facilitate different functions in the plants.
The main job of roots is to absorb and transport water. However in special cases, roots may get modified to store food, help in respiration and provide support. Depending on the need and type of plant, the adventitious or tap roots may be modified. Example- Carrot, Banyan tree.
The primary function of the stem is to produce and support lateral appendages and conduct food and minerals. However, it gets modified to perform additional functions such as storage of food, protection from browsing animals, perennation, proliferation and propagation. Example- Potato, strawberry, passion flower.
Leaves are green structures of plants mainly involved in photosynthesis. Besides photosynthesis and transpiration, they undergo modifications to provide support, to manage water loss by reducing transpiration. Example- Sweet pea, Cat’s nail.
