Quizplus · Accepted Answer

Binary fission is the process of a single cell dividing into two identical daughter cells, which is observed in prokaryotes and is responsible for the vertical components of the various bacterial and archaean lineages. Mitosis and meiosis are processes observed in eukaryotes, while sexual reproduction involves the fusion of gametes from two different individuals, which is not observed in prokaryotes.
