Detailed explanation-1: -Tubers. Tubers are swollen portions of an underground stem that store food so a plant can lie dormant over the winter, for example, potatoes. Axillary buds, commonly known as ‘eyes’, form over the surface of the tuber and produce shoots that grow into a new plant the following year.
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: -The type of stem which grows under the soil is known as an underground stem. The plants such as ginger, potato and colocasia have an underground stem.
