binary fission is a shorter and less complicated process of cell division compared to mitosis. What is the primary reason for this

Answer 1

The primary reason for this is that binary fission involves the division of a prokaryotic cell into two daughter cells, while mitosis involves the division of a eukaryotic cell into two identical daughter cells with a nucleus. Prokaryotic cells have a simpler structure without a nucleus, so the process of binary fission is simpler and requires fewer steps than mitosis.
