Taproot

Common card · No. 207531

A taproot is a large, central, and dominant root from which other roots sprout laterally and horizontally. Typically, a taproot is somewhat straight and very thick, is tapering in shape, and grows straight down. In some plants, such as the carrot, the taproot is a storage organ so well developed that it has been cultivated as a vegetable. The taproot system contrasts with the adventitious- or fibrous-root system of plants with many branched roots, but many plants that grow a taproot during germination go on to develop branching root structures, although some that rely on the main root for storage may retain the dominant taproot for centuries—for example, Welwitschia.
