vascular bundle

This term is a specialized botanical expression used primarily in scientific, academic, and biological contexts. It describes the integrated structural unit of a plant's transport system, emphasizing the physical proximity and functional cooperation between the xylem and phloem.

In a pedagogical or laboratory setting, the term is frequently used when discussing the anatomical differences between monocots and dicots, specifically regarding whether these bundles are scattered throughout the stem or arranged in a neat ring.
