Detailed explanation-1: -The vascular bundles in the stem are arranged around a ring of cambium, which contains cells that divide to expand the girth of the stem. This is similar to the function of the cambium in dicot roots.
Detailed explanation-2: -Dicot stems have their vascular bundles in a ring arrangement. Monocot stems have most of their vascular bundles near the outside edge of the stem. The bundles are surrounded by large parenchyma in the cortex region.
