Detailed explanation-1: -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.

Detailed explanation-2: -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-3: -Rhizome is also called creeping root stalk. It is a horizontal form of plant stem that grows underground which can form roots and shoots that grow into a new plant. Plants store starches and proteins in rhizomes and can survive unfavorable conditions by making use of this storage.

Detailed explanation-4: -Ginger, bamboo and irises are geophytes with underground stems known as rhizomes. Rhizomes grow horizontally in the soil and have nodes from which leaves can grow.

Detailed explanation-5: -Rhizomes are simply fleshy underground stems. They grow underground or right at ground level with many growing points or eyes similar to potatoes. Common examples of rhizomes include canna lilies, bearded Iris, ginger and bamboo.
