Explanation

Dicot stems possess conjoint, collateral, endarch and open vascular bundles. 'Conjoint' means xylem and phloem are together, 'collateral' means they're on the same radius, 'endarch' describes protoxylem facing inward, and 'open' means cambium is present for secondary growth. Monocot roots and stems have different arrangements - scattered vascular bundles in stems and radial arrangement in roots.
