Final answer:
Binary fission is a type of asexual reproduction observed in bacteria and other unicellular organisms, allowing for rapid population growth. It is an essential process for the survival and reproduction of prokaryotes.
Step-by-step explanation:
Binary fission is a type of asexual reproduction in which a parent cell splits into two identical daughter cells. This process is observed in bacteria, as well as in other unicellular organisms. Binary fission allows for rapid population growth under ideal conditions. It is an essential process for the survival and reproduction of prokaryotes.
