Binary fission is ...

• A. an asexual reproduction method in which a single cell splits into two cells.
• B. a sexual reproduction process.
• C. the migration of cells toward nutrients.
• D. a method of spore formation in bacteria.

Answer: (A)

Binary fission is an asexual mode of reproduction used by many bacteria and other prokaryotes. A single cell duplicates its circular chromosome, the copies attach to different parts of the cell membrane, the cell grows, and a septum forms to split the cell into two genetically identical daughter cells. There is no exchange of genetic material between cells during this process, which is why it does not involve sexual reproduction. It is not about cell movement toward nutrients (chemotaxis) and not about forming spores. In lab contexts, this mode of division explains how bacterial populations can double rapidly under favorable conditions.
