In what way is the structural organization of eudicot stems similar to that of monocot roots? In both groups, vascular bundles orlly contain one type of conducting tissue (xylem absent in the monocot roots' bundles, with phloem absent in the eudicot shoot). In both groups, vascular bundles are located in a central position (the stele) In both groups, vascular bundles are arranged in a circle, dividing the ground tissue into the cortex and pith In both groups, vascular bundles are scattered in a seemingly random fashion in the ground tissue In both groups, vascular bundles produce the cuticle that resists water loss and helps protect against attacks by microbes.
