vascular cambium definition
Lesson Summary. Vascular cambium is a thin layer of cells found in plants, separating two other types of plant vascular tissue, xylem and phloem. These cells divide and multiply with the plant's secondary growth, in which it increases in girth size.ylem, vascular tissue that transports water and nutrients through the plant, grows inward from the vascular cambium. Phloem, the vascular tissue that transports sugar and other large molecules, grows outward from the vascular cambium. When the vascular cambium cells divide, they create more xylem and phloem cells.
