Freshly dug sweet potato plants with tubers Hemerocallis tuber roots. A root tuber, tuberous root or storage root is a modified lateral root, enlarged to function as a storage organ. The enlarged area of the tuber can be produced at the end or middle of a root or involve the entire root.
Its root can attain lengths up to 2 m (6 + 1 ⁄ 2 ft) and weigh up to 20 kilograms (44 pounds). The heaviest jícama root ever recorded weighed 23 kg (51 lb) and was found in 2010 in the Philippines. [4] Jícama is frost-tender and requires nine months without frost for a good harvest of large tubers or to grow it commercially.
Tuberous roots or root tubers – Narrow sense, those storage roots that do not conform to a specific shape, such as fasciculated, nodulose moniliform, annulated, etc.: e.g. sweet potato (Ipomoea batatas), whose edible part is a root of this type. Broader sense, adventitious roots swollen due to their storage function.
In some species (e.g. Cyclamen coum) roots come from the bottom of the tuber, suggesting that it is a stem tuber; in others (e.g. Cyclamen hederifolium) roots come largely from the top of the tuber, suggesting that it is a root tuber. [6] As an example of a combination, juno irises have both bulbs and storage roots. [7]
The stem of a plant, especially a woody one; also used to mean a rootstock, or particularly a basal stem structure or storage organ from which new growth arises. Compare lignotuber. caudiciform Stem-like or caudex-like; sometimes used to mean "pachycaul", meaning "thick-stemmed". caudicle diminutive of caudex.

Root paste is externally applied as a poultice on cuts and wounds and extract is given in intestinal disorders. The term hatta haddi means a root (jadi) resembling a hand (hatta or hath).
Ulluco is one of the most widely grown and economically important root crops in the Andean region of South America, second only to the potato. [3] The tuber is the primary edible part, but the leaf is also used and is similar to spinach. [4] They are known to contain high levels of protein, calcium, and carotene.
Cyperus rotundus is a perennial plant, that may reach a height of up to 140 cm (55 in).The names "nut grass" and "nut sedge" – shared with the related species Cyperus esculentus – are derived from its tubers, that somewhat resemble nuts, although botanically they have nothing to do with nuts.
