Plant Stem Anatomy: Nodes, Internodes, and Petioles Explained #3219672 (License: Personal Use)

This botanical diagram illustrates the fundamental anatomy of a dicotyledonous plant stem, clearly labeling the node-the point where leaves or branches emerge-the internode, which is the elongated segment between two nodes, and the petiole, the stalk connecting the leaf blade to the stem. The structure demonstrates how vascular tissues run longitudinally through the stem and branch into petioles at nodes. Such diagrams are foundational in plant morphology education and horticultural training.

Used in educational resources like biology textbooks, online botany courses, gardening guides, and plant identification tools; targets students, teachers, hobbyist gardeners, and agricultural professionals seeking to understand plant growth patterns and pruning principles.
