Detailed explanation-1: -In monocot roots, xylem and phloem tissue bundles are arranged in a circular fashion around the central pith, which consists of ground tissue (parenchyma). Monocot roots have a larger number of vascular structures than dicot roots.

Detailed explanation-2: -The herbaceous stem is composed of vascular bundles (xylem and phloem) arranged in a circle around a central core of spongy tissue; this spongy tissue is composed of parenchyma cells and is called the pith.

Detailed explanation-3: -Monocot stem The vascular tissue is arranged into bundles of xylem and phloem that are scattered throughout the ground tissue. Within each bundle, the phloem is located closer to the outside of the stem, and the xylem is located closer to the inside of the stem.

Detailed explanation-4: -The monocot stem is composed of an epidermis, xylem and phloem (vascular bundles). The vascular bundles in a monocot stem are scattered throughout the origin of the stem underneath the epidermis. The scattered arrangement of the vascular bundles is a key characteristic that separates herbaceous dicots from monocots.

Detailed explanation-5: -Monocots have bundles of xylem and phloem mixed throughout their stem with vascular cambium between, an arrangement found on many herbaceous plants. Dicots, like trees and many woody stems, organize their parts in rings. A cork cambium, the growth layer, is found between the xylem and phloem in the ring.
