b. It bears roots
c. It is differentiated into nodes and internodes
d. It stores food

Answer 1

Hint: Ginger is an improved stem of a plant that typically grows parallel underground. It commonly has roots and shoots ascending from its nodes. The root is a fragment of a plant that possesses no leaves and thus lacks nodes.

Complete answer:
A rhizome (also recognized as rootstocks) is a type of plant stem located either at the soil surface or underground that comprises nodes from which roots and shoots initiate. Rhizomes are distinctive in that they grow steep, allowing new shoots to grow up out of the ground. When detached, each piece of a rhizome is skilled in creating a new plant.

Rhizomes are used to pile starches and proteins and allow plants to perennate (endure an annual unfavorable season) underground. Additionally, those adapted stems allow the parent plant to proliferate vegetatively (asexually), and some plants, such as bamboos, depend profoundly on rhizomes for that purpose.

In plants for example water lilies and many ferns, the rhizome is the solitary stem of the plant. In those cases, only the leaves and flowers are eagerly observable.
Therefore, ginger is a stem, not a root.

Hence, the correct answer is option (D).

Note: The chief function of the rhizome is the accumulation of nutrients, involving carbohydrates and proteins until the plant needs them for the development of new shoots or to persist the winter in a process called vegetative reproduction. Farmers utilize vegetative reproduction alongside propagating plants such as hops, ginger, and numerous grass species. Some rhizomes are also disbursed or used as a seasoning, including turmeric. Particularly, the rhizomes of some species counting turmeric and lotus are edible and appreciated for their cookery uses.
