Taproot

Taproot

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. 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 like grasses or annuals, which have a multitude of roots growing in different directions rather than one primary root.

Function

The primary function of the taproot is to anchor the plant into the ground, providing stability. Other functions of the taproot include absorption of water and nutrients from the soil and storing food reserves.
