What is the term for the section of the stem between two nodes?

The term for the section of the stem between two nodes is "internode." In botany, a node is the point on a stem where leaves or branches are attached, and the internode is the segment of stem that lies between two nodes. This structure plays a crucial role in plant growth and development, as it determines the spacing of leaves and can influence how light and nutrients are distributed throughout the plant. Understanding the function of internodes is important for various agricultural practices and for comprehending plant structure overall.

In contrast, the other terms refer to different anatomical features of a plant: a node identifies the specific points of attachment, an axil is the angle between a leaf and the stem, and a peduncle is the stalk that supports a flower or flower cluster. Each of these structures has its own distinct role in the plant’s morphology and growth patterns.
