Explanation: 

Detailed explanation-1: -Rhizomes are underground stems that grow on the soil surface. They grow horizontally and function as the organs of asexual reproduction and food storage. Rhizomes consist of nodes which develop roots and shoots that are growing perpendicularly to the ground. Each piece of rhizome with a node can grow into a new plant.

Detailed explanation-2: -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-3: -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-4: -The rhizome is the underground stem of turmeric, which can be divided into two parts, the central pear-shaped “mother rhizome” and its lateral axillary branches known as “fingers.” Normally, there is only one main axis. Either a complete finger or a mother rhizome is used as planting material.

Detailed explanation-5: -A rhizome (from Ancient Greek: rhízōma “mass of roots", from rhizóō “cause to strike root") is a characteristically horizontal stem of a plant that is usually found underground, often sending out roots and shoots from its nodes. Rhizomes may also be referred to as creeping rootstalks or rootstocks.
