Detailed explanation-1: -The Cell division in prokaryotes occurs through binary fission whereas in eukaryotes it may occur through mitosis or meiosis leading to the formation of the new cells.
Detailed explanation-2: -Mitosis is cell division that results in two identical daughter cells and is primarily used for growth of an organism. Binary fission is different from mitosis because prokaryotic cells do not have a true nucleus like eukaryotes. Also, there is no mitotic spindle formation in the nucleus during binary fission.
Detailed explanation-3: -Cell division by either binary fission or mitosis produces two genetically identical cells. This is the basis of asexual reproduction in single-celled organisms: prokaryotes reproduce by binary fission, and single-celled eukaryotes reproduce by mitosis.
Detailed explanation-4: -Unlike eukaryotes, prokaryotes (which include bacteria) undergo a type of cell division known as binary fission. In some respects, this process is similar to mitosis; it requires replication of the cell’s chromosomes, segregation of the copied DNA, and splitting of the parent cell’s cytoplasm.
Detailed explanation-5: -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.
