Vascular Cambium

 

• The vascular cambium is a cylindrical tissue consisting predominantly of elongated cells that divide frequently.
• It is the layer of calls(cambium) that arise within vascular bundles
• LOCATION: Within Vascular Bundles.
• FUNCTION: It produces cells of secondary Xylem and Secondary Phloem
• The vascular cambium is initially a single layer of cells lying between the primary xylem and the primary phloem within the vascular bundles.
• As the root or stem increases in diameter when the cells of the vascular cambium divide, producing secondary xylem cells toward the inside of the root or stem and producing secondary phloem cells toward the outside.
• The principal cell products of the vascular cambium are vessel elements, tracheids, and supportive fibers in the secondary xylem, and sieve tube elements, companion cells, fibers, and parenchyma cells in the secondary phloem.
