Plants have three types of root systems: 1.) taproot, with a main taproot that is larger and grows faster than the branch roots; 2.) fibrous, with all roots about the same size; 3.) adventitious, roots that form on any plant part other than the roots. Fibrous systems are characteristic of grasses and are shallower than the taproot systems found on most eudicots and many gymnosperms.
