Bacteria cells reproduce by binary fission, a type of asexual cell division. One advantage of binary fission is

Binary fission is a asexual reproduction. Mostly it occur in bacteria. In binary fission DNA replication and segregation occur simulataneously. Example of binary fission is amoeba.

Advantges of binary fission:

1) The advantage of binary fission is it is very fast (approx - 20min genration for some bacteria.)

2) As it is a asexual reproduction, it requires single organism.

Binary fission is the process of cell division used in most of the unicellular organisms. It is very much similar to the mitotic division in the multi-cellular organisms. In bacteria's, cells dividing by binary fission copy its DNA. DNA replication during binary fission actually happens at the same time as DNA separation and thus the new cells formed are identical to each other.
