Answer by Omkar Jilla
@ayushi, polyarch condition is true for both monocot roots and dicot roots, but dicot roots comparatively has more no. of vascular bundles, and hence more no. of xylem arches. So here dicot roots will be more correct; it doesn't matter if NCERT hasn't mentioned any statement on it as it can be easily understood by diagram itself.
