Detailed explanation-1: -The Dicot root contains radial vascular bundles. In the center, there is a small parenchymatous pith. It is also possible that dicot roots lack it. There are 2 to 6 vascular bundles in the dicot root.
Detailed explanation-2: -Because of the presence of cambium the vascular bundles of dicot stem are open.
Detailed explanation-3: -For example, monocots have their vascular bundles scattered in the stem, while eudicots have them organized in a ring around the stem (Chapter 3). In monocots, like corn, these vascular bundles are scattered throughout the stem tissue. Eudicots, like beans, are a little more complex.
Detailed explanation-4: -In dicot roots, the vascular structures are located in the middle of the root. The arrangement of xylem and phloem is different in dicots than it is in monocots. The xylem is all located in the middle of the dicot root, and bundles of phloem are arranged around it, separated from it by vascular cambium.
Detailed explanation-5: -Bicollateral vascular bundles are always open.
