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: -Ferns have 3 major parts – the rhizome, the fronds and the reproductive structures called sporangia. The characteristics of each of these 3 parts of the fern plant are used for classification and identification. The rhizome is the stem of the fern plant.

Detailed explanation-3: -Some of the examples of underground rhizomes are hops, ginger, bamboo, poison oak, and grass species. Most of these rhizomes are edible to humans.

Detailed explanation-4: -rhizome, also called creeping rootstalk, horizontal underground plant stem capable of producing the shoot and root systems of a new plant. Rhizomes are used to store starches and proteins and enable plants to perennate (survive an annual unfavourable season) underground.
