When cells divide, they make new cells. A single cell divides to make two cells and these two cells then divide to make four cells, and so on. We call this process cell division and cell reproduction, because new cells are formed when old cells divide. The ability of cells to divide is unique for living organisms.
Cell division (above) can be a matter of simple fission, as described on this page, which occurs only in prokaryotes. Or it can occur via either of the two more complex processes, meiosis and mitosis, characteristic of eukaryotes. Before fission can occur, the cell must replicate its chromosome, which is circular.
