taproot (redirected from Taproots)

taproot

Main root of a primary-root system. It grows vertically downward. From the taproot arise smaller lateral roots (secondary roots), which in turn produce even smaller lateral roots (tertiary roots). Most dicotyledonous plants (see cotyledon), such as dandelions, produce taproots. The system may be modified into a fibrous, or diffuse, system, in which the initial secondary roots soon equal or exceed the primary root in size and there is no well-defined single taproot. Fibrous root systems are generally shallower than taproot systems. Carrots and beets are tuberous roots modified from taproots.
