Here's why:
* No nucleus: Prokaryotes lack a nucleus and other membrane-bound organelles. Therefore, they don't have the same complex chromosomal structure as eukaryotic cells.
* Single circular chromosome: Prokaryotes have a single, circular chromosome located in a region called the nucleoid.
* Simpler division: Binary fission is a simpler and faster process compared to mitosis. It involves the following steps:
* DNA replication: The single chromosome replicates.
* Cell elongation: The cell elongates, and the replicated chromosomes move to opposite ends.
* Cell division: The cell membrane pinches inward, eventually dividing the cell into two identical daughter cells.
In summary: Prokaryotes use binary fission for reproduction, not mitosis. Mitosis is a complex process involving multiple stages and is specific to eukaryotic cells.
