Stem Cross-Section: Dicot vs Monocot Dicot: bundles in a RING Monocot: bundles SCATTERED In a dicot stem, vascular bundles are arranged in a single ring (with cambium between xylem and phloem, enabling secondary growth); in a monocot stem, bundles are scattered throughout with no cambium, so monocots can't undergo secondary growth (no wood formation).
