Explanation: 

Detailed explanation-1: -The difference between dicot and monocot roots is that monocot roots are fibrous roots, they have a wide network of thin roots that emerges from the stem. Dicots, on the other hand, have taproots, which means that they form a single thick root from which small, lateral branches emerge.

Detailed explanation-2: -In monocot roots, the number of xylem and phloem bundles are polyarch (more than 6 vascular bundles) while in dicots, the number of vascular bundles usually varies from diarch to hexarch.

Detailed explanation-3: -Anatomy of monocot stem The Monocot Stem has Vascular Bundles near the outside edge of Stem. Vascular Bundles are scattered in Parenchymatous ground Tissue. There is no pith region in Monocots. Dicot Stems have bundles in a ring surrounding Parenchyma cells in a pith region.
