Question

Quizplus · Accepted Answer

A taproot is a single main root that grows downward and is adapted for storage. It is typically larger and goes deeper than other roots. Tuber and rhizome are both types of roots, but they are not necessarily adapted for storage and do not grow downward. Fibrous roots are a system of many small, shallow roots rather than a single main root.
