Modification of Tap Root
Roots of some plants modify their structure, shape, etc.
These modifications are performing functions, other than absorption and conduction of water and minerals.
Modified roots may perform functions such as support, respiration, and storage.
This figure is taken from NCERT book , Class XI from page no.68.
A persistent taproot system forms when the radicle keeps growing and smaller lateral roots form along the taproot. The shape of taproots can vary but the typical shapes include:
- Conical root: this type of root tuber is conical in shape, i.e. widest at the top and tapering steadily towards the bottom: e.g. carrot.
- Fusiform root: this root is widest in the middle and tapers towards the top and the bottom: e.g. radish.
- Napiform root: the root has a top-like appearance. It is very broad at the top and tapers suddenly like a tail at the bottom: e.g. turnip.
Many taproots are modified into storage organs.
