Detailed explanation-1: -Prokaryotes, which include bacteria and single-celled microorganisms called Archaea, usually pass their chromosomal DNA on to their offspring asexually. In other words, a bacterial cell reproduces by simply replicating its chromosome and dividing into two daughter cells.
Detailed explanation-2: -Bacterial binary fission is the process that bacteria use to carry out cell division. Binary fission is similar in concept to the mitosis that happens in multicellular organisms (such as plants and animals), but its purpose is different.
Detailed explanation-3: -In unicellular organisms such as bacteria, mitosis helps in asexual reproduction as it produces an identical copy of the parent cell. Another example of the Eukaryotic unicellular organism is “Amoeba.” An amoeba uses cell division for the production of new individuals.
