The Root

Root modification means permanent structural changes in the roots. Some examples of modified roots are radish (fusiform root), turnip (napiform root), carrot (conical tap root), sweet potato (tuberous root), Portulaca (moniliform root), Curcuma sp (nodulose root) etc.

The root hanging from the branch of banyan tree are prop root, which are developed from the main branches of tree. These root grow straight downward to the soil, which they enter and form underground root. Due to secondary growth these became thick and provide mechanical support to the plant. Fibrous root may be given off in cluster from the base of stem e.g., onion or from the node of creeping branches of grasses. Neumatophore are characteristic root of mangroove plant, which are responsible for gaseous exchange.
