It gives rise to the vascular tissues of phloem and xylem. Thus it helps in the secondary growth of a plant.
i think it is vascular cambium layer............ :)
The function of vascular cambium in dicots is to give rise to new vascular tissue.
The vascular cambium tissue makes xylem and phloem.
woody stems have more xylem than soft stems
xylem tissue and phloem tissue, which both come from the vascular cambium
Vascular Cambium
Vascular cambium
Lateral meristems. Usually, vascular tissue is produced in the center of the stalk and grows outward continually. The vascular cambium is responsible for the new vascular tissue and the cork cambium produces new dermal coverings.
The vascular tissue is the organ of the plant that may form the cork cambium.
I believe it is the vascular cambium layer, not %100
In these rings itself the vascular tissue, specially the xylem is gathered in a tree. The phloem remain peripheral to these rings.
Secondary growth is important because as larger plants grow, more vascular tissue (responsible for transport of water, sugar and minerals) is needed to keep up with the constant growing of the plant. Limit the vascular tissue and the plant will have insufficient amount of water and sugar conduit for transportation throughout.
