Detailed explanation-1: -The steles of dicot roots contain a layer of meristem cells, called the cambium (or vascular cambium), located between the xylem and phloem.

Detailed explanation-2: -Dicot root 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-3: -The stele is composed of mainly three tissues which are the pericycle, the xylem, and the phloem. In the outer side of the stele, there is the endodermis present, which is the innermost cell layer of the cortex.

Detailed explanation-4: -The vascular bundle is always radially arranged in the dicot roots. Furthermore, the xylem in a dicot root is always exarch.

Detailed explanation-5: -Endodermis is followed by pericycle, which are a few layers of thick-walled parenchyma cells. In dicots, the central pith is not distinct. There are two to four xylem and phloem. The xylem and phloem are remarked by a layer of parenchymatous cells known as conjunctive tissue.
