Detailed explanation-1: -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.

Detailed explanation-2: -The stem is long, slender and freely-branched rhizome of indefinite growth that grows on or just below the soil surface. It is differentiated into nodes and internodes. The internodes are generally long in aquatic species but are short in sub-terrestrial or terrestrial species.

Detailed explanation-3: -Thus, internally rhizome consist of epidermis, cortex, followed by stele which is made up of outer endodermis, outer pericycle, outer phloem, xylem, inner phloem, inner pericycle and inner endodermis.

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.
