Detailed explanation-1: -A taproot is a large, central, and dominant root from which other roots sprout laterally. Typically a taproot is somewhat straight and very thick, is tapering in shape, and grows directly downward.

Detailed explanation-2: -A tap root system penetrates deep into the soil. In contrast, a fibrous root system is located closer to the soil surface, and forms a dense network of roots that also helps prevent soil erosion (lawn grasses are a good example, as are wheat, rice, and corn).

Detailed explanation-3: -taproot, main root of a primary root system, growing vertically downward. Most dicotyledonous plants (see cotyledon), such as dandelions, produce taproots, and some, such as the edible roots of carrots and beets, are specialized for food storage.

Detailed explanation-4: -A taproot is typically a long vertical, somewhat thickened root that is deeply anchored in the soil. Taproots are the first roots to emerge from the seed, although smaller lateral roots eventually branch from the taproot, increasing water and mineral absorption capacity.

Detailed explanation-5: -Below ground, the taproot will continue growing through that first year, sometimes reaching as much as four feet in depth. Feeder roots develop along much of the depth of this taproot, forming a deeply rooted, difficult to dig plant.
