Answer 2

Underground stems are modified plants that derive from stem tissue but exist under the soil surface.They function as storage tissues for food and nutrients, propagation of new clones, and perennation (survival from one growing season to the next). Types include bulbs, corms, rhizomes, stolons, spindle-shaped[citation needed], and tubers.

Different forms of underground stems include:

Bulb - Short, upright organ leaves modified into thick flesh scales. Tulips, daffodils and Lilies.

Corm - Short, upright, hard or fleshy stems covered with thin, dry papery leaves.

Rhizome - With reduced scale like leaves. The top can generate leafy stems while the bottom can produce roots. Iris.

Stolon - Horizontal stems that run at or just below the soil surface with nodes that root and long internodes, the ends produce new plants. When above ground they are called "runners".

Tuber - An enlarged fleshy end of a stem, generally from rhizomes but often also referring to thickened roots too.
