What is the portion between two nodes called?

• A. Stilt Roots
• B. Nodes
• C. Internodes
• D. Pulvinous

Answer: (C)

On a plant stem, the segments between attachment points are called internodes. A node is the point where a leaf or bud attaches, so the stretch of stem between two such points is the internode. This distinction helps explain plant form, since longer internodes make the plant taller with more spacing between leaves, while shorter internodes create a more compact habit. The other terms refer to different structures: stilt roots are aerial roots for extra support, and a pulvinus is a swollen leaf base that aids movements, not a stem segment.
