Question

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

Answer 1

The correct option is B Rhizomes have scale leaves

Some plants have rhizome and roots as underground structures but rhizomes differ from roots in having scale leaves. A rhizome is a modified subterranean stem of a plant that is usually found underground. Rhizomes are also called creeping root stalks and root stocks. The nodes of rhizomes have dry scale leaves with axillary buds. They have a specialized lateral growth pattern in which the apical meristem is terminated and make it different from the roots.

Thus, the correct answer is option B.
