Summary Introduction
Concept introduction: The eudicot taproot along with its lateral root branching constitutes the taproot system. In some eudicots, the taproots are eventually replaced by the adventitious roots. Therefore, a taproot system can also develop into a fibrous root system. Carrot is a prime example of a taproot.
