Internodes

Stems are composed of repeating units called internodes.

To determine the answer to the question, you can either have prior knowledge of the topic or conduct research. In this case, the repeating units that make up stems are called internodes.

Internodes are the sections of a stem between two nodes. A node is the part of a stem where leaves, buds, or branches originate. Internodes are the elongated segments of a stem that grow between nodes. They are responsible for providing structural support and allowing the stem to grow in length.

By understanding the basic structure and terminology of a stem, you can identify that the repeating units are referred to as internodes.
