secondary phloem
Quick Summary
Secondary phloem is plant vascular tissue produced by the vascular cambium. This tissue is responsible for transporting sugars, or foods produced during photosynthesis in the leaves, to other parts of the plant. It is a component of the secondary vascular system, which develops in woody plants.123
The vascular cambium, a lateral meristem, generates secondary phloem to the outside and secondary xylem to the inside. As the vascular cambium produces more secondary xylem, the older, outer layers of secondary phloem are crushed and eventually shed as part of the bark. This process contributes to the growth and structural development of woody plants.23

angiospermSecondary vascular systemThe secondary phloem of angiosperms consists of sieve-tube members, companion cells, scattered parenchyma, ray parenchyma, and fibers. The fibers usually occur in clusters or as bands alternating with bands of sieve tubes and parenchyma cells. As the vascular cambium continues to produce more secondary xylem to…
