Functions types and Morphology of Roots

1. Fixation: Root provides anchorage to the plants. It also provides mechanical support to the aerial parts against gravity and wind.

2. Absorption: Roots absorb water and minerals from soil by its root hair.

3. Conduction: It is also concerned with upward transport or conduction of water and minerals to the stem.

4. Prevention of soil erosion: Roots hold the soil particles firmly to prevent soil erosion.

5. Storage: Fleshy roots store food materials.

6. Mechanical support: Several types of modified adventitious roots provide mechanical support to the plants.

7. N2-fixation: Nodulated roots of legumes fix nitrogen.

8. Reproduction: Vegetative reproduction takes place by the radical buds.

9. Photosynthesis: Assimilatory roots manufacture food.

10. Balancing: Free floating plants are balanced in water by a cluster of adventitious roots.

11. Aeration: Pneumatophores of mangrove plants help in respiration.
