Amoebas and other unicellular cells which use mitosis or binary fusion

1.	Amoebas and other unicellular cells which use mitosis or binary fusion, do they ever age? If not how do they die, why don't we have world full of them? .
Answer» Prokaryotes such as bacteria propagate by binary fission. ... In bacterial cells, the genome CONSISTS of a single, circular DNA chromosome; therefore, the PROCESS of cell division is simplified. Mitosis is unnecessary because there is no NUCLEUS or MULTIPLE chromosomes. This TYPE of cell division is called binary fission.
