A type of cell division that allows for asexual reproduction in bacteria and many other unicellular organisms is called fission.

Fission is a form of asexual reproduction predominantly observed in single-celled organisms, including bacteria. During this process, a parent cell divides into two or more daughter cells, each receiving a copy of the parent cell's genetic material. There are various forms of fission, but the most common in bacteria is binary fission, where the cell grows, duplicates its DNA, and divides in half.

This method of reproduction is advantageous for organisms in stable environments, allowing for rapid population growth. Since fission does not require a mate, it enables bacteria to quickly multiply under favorable conditions. However, the lack of genetic variation in offspring can be a disadvantage in changing environments, where diversity might enhance survival.
