Detailed explanation-1: -The xylem rings represent the age of the plant as a result of the fluctuating activity of the vascular cambium in a year, and since it is 3 years old there will be 3 rings of the xylem present and contains 1 phloem.
Detailed explanation-2: -The vascular bundles are arranged in circular pattern in dicots and monocot root. It is randomly dispersed in monocot stem. No, the vascular bundles in both dicots and monocots are arranged in the same way.
Detailed explanation-3: -Secondary Growth and Annual Rings The activity of the vascular cambium results in annual growth rings. During the spring growing season, cells of the secondary xylem have a large internal diameter and their primary cell walls are not extensively thickened. This is known as early wood, or spring wood.
Detailed explanation-4: -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.
