The fibrous-root system (A) is characterized by many roots with similar sizes. In contrast, plants that use the taproot system (B) grow a main root, with smaller roots branching off. The letters indicate where the root systems begin. A taproot is a large, central, and dominant root from which other roots sprout
The plant forms a fleshy tap root that is used as a storage and overwintering structure. [12] The central tap root can weigh up to 72 kg (159 lb). A four-year-old root grown under cultivation can reach a fresh weight of 45 kg (99 lb) and a length of 2.5 m (8.2 ft). [5]
Big sagebrush is a coarse, many-branched, pale-grey shrub with yellow flowers and silvery-grey foliage, which is generally 0.5–3 metres (1 + 1 ⁄ 2 –10 feet) tall. [3] A deep taproot 1–4 m (3 + 1 ⁄ 2 –13 ft) in length, coupled with laterally spreading roots near the surface, allows sagebrush to gather water from both surface precipitation and the water table several meters beneath.

In its broader sense, a tap-root that is thick and fleshy (due to storage); i.e. when tuberation take place in a tap-root. Pneumatophores (respiratory roots) – Part of tap-root system as respiratory roots; found in many mangrove trees. They arise from the thick, mature branches of tap-root systems, and grow upwards.
It is drought resistant, possibly because of its long taproot. At the end of the growing season, a one-year sapling may have a taproot 1.37 m (4 + 1 ⁄ 2 ft) deep and a lateral root spread of 76 cm (2 + 1 ⁄ 2 ft). [10] The West Virginia state champion bur oak has a trunk diameter of almost 3 m (10 ft).
The parsnip is a biennial plant with a rosette of roughly hairy leaves that have a pungent odor when crushed. Parsnips are grown for their fleshy, edible, cream-colored taproots.
