As compared to a dicot root, a monocot root typically has many xylem bundles scattered throughout the cross-section of the root, whereas a dicot root typically has a central vascular cylinder with a distinct arrangement of xylem and phloem in the form of a central vascular bundle. Inconspicuous annual rings (statement 2) are typically not a characteristic feature of monocot roots, as annual rings are usually associated with secondary growth in woody dicot roots and stems. Relatively thicker periderm (statement 3) is not a characteristic feature of monocot roots, as periderm is typically absent or thin in monocots, whereas it is a significant component of secondary growth in woody dicot roots and stems. More abundant secondary xylem (statement 4) is not a characteristic feature of monocot roots, as secondary growth and the formation of secondary xylem are typically limited in monocots, whereas they are prominent in woody dicot roots and stems.
