Secondary growth involves the activity of the vascular cambium and cork cambium, which differentiate and produce secondary tissues such as secondary xylem (wood) and cork. Primary growth, on the other hand, occurs from the activity of the shoot or root apical meristems and involves elongation of the plant body through cell division and elongation, without the formation of secondary tissues.
