'''Tubers''' are a type of enlarged structure that [[plant]]s use as [[storage organ]]s for [[nutrient]]s, derived from stems or roots. Tubers help plants [[perennate]] (survive winter or dry months), provide energy and nutrients, and are a means of [[asexual reproduction]].<ref name="rooting_cuttings_of_tropical_trees">{{Citation |title=Rooting Cuttings of Tropical Trees |pages=11 |year=1994 |location=London |publisher=Commonwealth Science Council |isbn=978-0-85092-394-0}}</ref>

'''Stem tubers''' manifest as thickened [[rhizome]]s (underground stems) or [[stolon]]s (horizontal connections between organisms); examples include the [[potato]] and [[Yam (vegetable)|yam]]. The term '''''root tuber''''' describes modified lateral [[root]]s, as in [[sweet potato]]es, [[cassava]], and [[dahlia]]s.
