The functions of various parts of a plant are as below.

1. Root: 

(a) Fixation: It anchors the plant body to the soil, so helps in fixation, 

(b) Absorption: It absorbs water and nutrients from the soil, so helps in absorption, 

(c) Conduction: The root translocates water and mineral salts into the stem. 

(d) Storage: A certain amount of food is stored in the root which is utilized as it grows.

2. Stem: 

(a) It supports and holds leaves, flower and fruits, 

(b) The stem conducts the water and minerals from roots to leaves and fruits, 

(c) It stores the food. 

3. Leaves: 

(a) It synthesizes food for the plant, 

(b) Stomata, the tiny openings in the leaf help in gaseous exchange and are responsible for the process of transpiration.

4. Flower: It helps in pollination.

5. Fruit: 

(a) It protects the seed,
