This tissue is classified by the order of maturation as either proto- or meta-; it may be further classified by origin as primary or secondary, the latter type emerging from the vascular cambium. Ernst Munch deduced the operation of this system in 1930 with his pressure flow hypothesis. Generally occurring just inside the fibral sclerenchyma, it consists of sclereids, albuminous cells, companion cells, and sieve-tube cells. The fluid that it carries is known as photosynthate and is rich in nutrients. For 10 points, name this vascular tissue in plants that compliments the xylem.
