The correct sequence starting from the exterior of the plant with the outermost layer of stem tissue, and moving toward the center is primary phloem, secondary phloem, secondary xylem, primary xylem. This is because the primary phloem is the outermost layer of the stem, followed by secondary phloem, which is produced by the vascular cambium. The secondary xylem is produced by the vascular cambium and placed towards the center, followed by primary xylem, which is the innermost layer of the stem.
