Tap-Root-System: Storage roots: Conical root – Storage root that is broad at its base (upper portion) and gradually tapers to its apex (lower portion): e.g., Carrot. Fusiform root – Storage root that is swollen in the centre and tapers towards both apex and base: e.g., radish (Raphanus sativus).
The enlarged area of the tuber can be produced at the end or middle of a root or involve the entire root. It is thus different in origin, but similar in function and appearance, to a stem tuber. Plants with tuberous roots include the sweet potato ( Ipomoea batatas ), cassava , dahlia , and Sagittaria (arrowhead) species.
