3. Rhizome - Wikipedia

   en.wikipedia.org/wiki/Rhizome

   In botany and dendrology, a rhizome (/ ˈ r aɪ z oʊ m / RY-zohm) [note 1] is a modified subterranean plant stem that sends out roots and shoots from its nodes.

   In most plants, stems are located above the soil surface, but some plants have underground stems. Stems have several main functions: [3] Support for and the elevation of leaves, flowers, and fruits. The stems keep the leaves in the light and provide a place for the plant to keep its flowers and fruits.

7. Vegetative reproduction - Wikipedia

   en.wikipedia.org/wiki/Vegetative_reproduction

   Tubers develop from either the stem or the root. Stem tubers grow from rhizomes or runners that swell from storing nutrients while root tubers propagate from roots that are modified to store nutrients and get too large and produce a new plant. [22] Examples of stem tubers are potatoes and yams and examples of root tubers are sweet potatoes and ...
