The most basic characteristic of life is reproduction. Reproduction occurs at different levels of organization. Parts of cell such as chromosomes produce new chromosomes, cells produce new cells and individuals produce offspring like themselves. If we recall from chapter 1, we should remember Rudolf Virchow. He proposed an important biological principle i.e. all cells come from cells. This principle tells us that the continuation of life, including all aspects of reproduction, is based on the reproduction of cells. We commonly refer cellular reproduction as cell division and it is a part of the whole life of a cell i.e. cell cycle. All cells come from cells. This principle was proposed by?
