Taproot System In plants the primary root originates in the embryo from the radicle. In gymnosperms and most dicots, the primary root becomes a taproot, growing directly downward and giving rise to lateral roots. A taproot and its branches make up the taproot system.

  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.
