Cell Division: The German biologist Walter Flemming was the first, who observe the process of cell division, and gave it the term mitosis. A cell division is a process by which a single cell multiplies in number. A growing cell undergoes interphase (a period of non-apparent division) and the period of division. In interphase, cell doubles in size and chromosomes duplicate. Therefore, cell division can be considered a process of ensuring exact duplication of cellular information and its equal distribution to the two daughter cells. Thus, the two type of cell divisions observed, are mitosis and meiosis.
