Answer:

Binary fission is different from mitosis and meiosis because it occur in prokaryotic cells. And prokaryotic cells does not have nucleus like the eukaryotic cells and there is not mitotic spindle formation during binary fission compared to mitosis and meiosis.

Explanation:

Binary fission is a process of cell division where a single cells divide into two or more parts and the parts regenerate into another organisms which resembles the parent organisms. This occur only in prokaryotic cells and is very different from mitosis and meiosis that occur in eukaryotic cells because prokaryotic cells lack nucleus and no spindle formation in the nucleus.

Mitosis occur in eukaryotic cells because they have nucleus and membrane bound organelles and is the process where a parent cell divide to produce two daughter cells that are genetically identical to the parent cell and each cell having the same number of chromosomes of the parent cell.

Meiosis is a type of cell division that occur in eukaryotic cells and it occur in sex cells where a single cell divide into four daughter cells with each having half number of parent cell chromosomes.
