Some plants have rhizome and roots as underground structures. Which of the following characteristics of rhizome would distinguish them from roots?
A. Rhizomes are thicker than roots
B. Rhizomes have scale leaves
C. Rhizomes are thinner than roots
D. None of the above

Hint: A rhizome is a robust even stem of a plant, generally discovered underground, and frequently spreading out roots and shoots from its nodes. Its source comes from the Greek word "rhizome," which signifies "mass of roots." Rhizomes are basically underground changed stems. They create corresponding to the Earth's surface having hubs and internodes as stems, little leaves, and buds. Rhizomes function as food stockpiling and help in vegetative spread which is a strategy for developing rhizome pieces into new plants.

Complete answer:
A few plants have rhizomes and roots as underground structures however rhizomes contrast from establishing scale leaves. A rhizome is an altered underground stem of a plant that is generally discovered underground. Rhizomes are additionally called crawling root stalks and root stocks. The hubs of rhizomes have dry scale leaves with axillary buds. They have a particular horizontal development design in which the apical meristem is ended and make it not quite the same as the roots
Rhizome, likewise called crawling rootstalk, even underground plant stem fit for delivering the shoot and root frameworks of another plant. Rhizomes are utilized to store starches and proteins and empower plants to perennate (endure a yearly troublesome season) underground. What's more, those changed stems permit the parent plant to spread vegetatively (agamically), and a few plants, for example, poplars and different bamboos, depend vigorously on rhizomes for that reason. In plants, for example, water lilies and numerous greeneries, the rhizome is the main stem of the plant. In such cases, just the leaves and blossoms are promptly obvious.

Hence, the correct answer is option (B).

Note: Plants that have rhizomes incorporate poplars, bamboos, ginger, turmeric, lotus, and numerous kinds of greeneries. Irises are additionally important for the rhizome family. A portion of these rhizomes are palatable and searched out as a delicacy. Eminently, the rhizomes of certain species—including ginger, turmeric, and lotus—are consumable and esteemed for their culinary applications.
