How does a bacterium reproduce?

Mitosis is a process associated with eukaryotic cell division, where a single cell divides to produce two identical daughter cells. While it involves a complex series of steps and is essential for growth and repair in multicellular organisms, bacteria do not undergo mitosis due to their simpler cellular structure and lack of a defined nucleus.

Meiosis is a specialized form of cell division that produces gametes (sperm and egg cells) in sexually reproducing organisms. It involves two rounds of division and results in four genetically diverse cells. Since bacteria reproduce asexually and do not form gametes, meiosis is not applicable to bacterial reproduction.

Cytokinesis is the process that follows mitosis or meiosis, where the cytoplasm of a parental cell divides into two daughter cells. While it is a critical step in cell division for eukaryotes, it is not a method of reproduction in bacteria. Instead, cytokinesis is part of the binary fission process itself in prokaryotes.
