Detailed explanation-1: -Rhizomes are underground stems which grow beneath the surface of soil; they are frequently fleshy and serve as organs of food storage. Sometimes the rhizomes are condensed into solid swollen forms which are then known as corms. The tubers are also underground parts, which may either be modified roots or stems.

Detailed explanation-2: -rhizome, also called creeping rootstalk, horizontal underground plant stem capable of producing the shoot and root systems of a new plant.

Detailed explanation-3: -Ferns do not have aerial stems in the manner of many other vascular plants. Instead, the leaves arise directly from an underground stem (rhizome) or a very short vertical stem at or near the soil surface.

Detailed explanation-4: -A rhizome is a modified stem that grows horizontally underground; it has nodes and internodes. Vertical shoots may arise from the buds on the rhizome of some plants, such as ginger and ferns. Corms are similar to rhizomes, except they are more rounded and fleshy (such as in gladiolus).

Detailed explanation-5: -Adventitious roots and storage roots arise from the nodes of these rhizomes.
