Functions of Roots

Anchorage

Roots anchor the plant firmly to the soil (mechanical function).

Absorption

Roots absorb water and mineral salts and conduct them upwards (physiological function).

Special Functions

By undergoing modifications in their structure, roots perform special physiological functions like food storage, assimilation, absorption of atmospheric moisture, sucking food from host, better gaseous exchange and mechanical functions like floating (buoyancy), stronger anchorage and climbing.
