Dicot stems have vascular bundles arranged in ring around a core of pith - with primary xylem to the inside and primary phloem to the outside - vascular cambium is found between xylem and phloem Monocot stems have vascular bundles scattered throughout ground tissue - have no vascular cambium - so secondary growth is not possible
Secondary growth Vascular cambium produces secondary xylem to inside and secondary phloem to outside secondary xylem is wood and is added in sequential layers phloem is thin-walled and is older layers are crushed as new layers are produced and stem increases in girth Cork cambium arises in cortex and produces new cork to outside
