<P> Tubers are enlarged structures in some plant species used as storage organs for nutrients . They are used for the plant 's perennation ( survival of the winter or dry months ) , to provide energy and nutrients for regrowth during the next growing season , and as a means of asexual reproduction . Stem tubers form from thickened rhizomes ( underground stems ) or stolons ( horizontal connections between organisms ) . Common plant species with stem tubers include potato and yam . Some sources also treat modified lateral roots ( root tubers ) under the definition ; these are encountered in sweet potato , cassava , and dahlia . </P>
