Which vascular bundle arrangement is typical of dicotyledonous stems, where xylem and phloem strands are situated on the same radius with a cambium layer between them?

💡 Solution & Explanation

Dicotyledonous stems feature conjoint, collateral, and open vascular bundles, meaning xylem and phloem lie on the same radius with an active cambium layer that permits secondary growth. Radial bundles have xylem and phloem on alternate radii, common in roots rather than stems. Closed bundles lack cambium and cannot undergo secondary thickening. Concentric bundles have one vascular tissue completely surrounding the other without cambial participation.
