How do prokaryotes reproduce?

I find different answers on the internet. Do they divide by binary fission, or by mitosis?

Answer

~~Prokaryotes, also called bacteria, multiply by binary fission. The binary division is an asexual reproduction in which a cell divides into 2 identical daughter cells. To form those 2 identical daughter cells, the DNA of the mother cell is first doubled. The 2 identical DNA molecules are pulled apart, making the cell elongate. In between the 2 DNA molecules, notches are created in the cell wall and the plasma membrane. From here, a double wall is formed between the 2 DNA molecules. Subsequently, the 2 newly formed daughter cells separate from each other (cytokinesis). These daughter cells are identical to the parent cell.

Mitosis only occurs in eukaryotic organisms where 2 new cells arise from an old cell. These 2 newly formed cells are identical to the old cell from which they originated. Mitosis largely resembles the binary division in bacteria, but mitosis uses a spindle to separate the chromatids of the chromosomes and distribute them over the 2 new cells, while that spindle does not occur in the binary division of bacteria.
