something that provides an important central source for growth or development; "the taproot of his resentment"; "genius and insanity spring from the same taproot"
Large, vertical root with many smaller lateral roots Taproots usually go deep into the soil and provide the plant a strong anchor Taproots are characteristic of many dicots
Carrots are essentially a swollen taproot Plants with a taproot have a primary root from which the finer roots stretch Often, plants with taproots are able to probe deeper into the subsoil to reach water and nutrient resources and are therefor more able to withstand drought Compare with fibrous root systems
the main anchoring root which grows muach larger than the secondary roots tomentose- covered with wooly hairs trigonal- triangular in cross section triocular- having three changers or cells trilocular- having three chanbers or cells tripinnatisect- a leaf in which the pinnately divided leaflets are themselves pinnately divided triploid- having a chromosome number that is three times the basic, or haploid, number tuber- a swollen, underground stem contaning a sotre of nutritive materials turion- a fleshy, underground bud shooting up from the stem
the large main root of a plant, from which smaller roots grow. 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
