Vascular bundles are radial; Xylem is exarch, number of xylem bundles varies from 2 to 4 rarely more (upto 6-8). Metaxylems are angular arranged in linear.Dicot vascular tissue forms a cylinder near the center of the stem. Monocot roots, interestingly, have their vascular bundles arranged in a ring. Dicot roots have their xylem in the center of the root and phloem outside the xylem.
