Schwann, and his fellow German Mathias J. Schleiden, brought the science of cellular biology into being. "In 1838 Schwann recognised the ovum to be a cell and drew from this epochal decision three conclusions: that the entire plant or animal consists of a grouping of cells or cellular derivatives; that each cell has a certain amount of individual life; that each cell life is subject to that of the organism as a whole. These concepts still prevail. The cell (so named by Hooke) thus became thge building block for the entire structure of plant and animal life and provides the distinction between a living and a dead organism" (Dibner).
