    the vascular bundle can either be radial or conjoint

    radial: the components of the vascular bundle (xylem & phloem) are arrange separaetly in different radii. - typically found in roots of monocots and dicots.

    conjoint: xylem and phloem are arranged together in the same radius - this is seen in the stem and leaves
