WebIf an organism could be grown on an agar plate or in a liquid culture, then it could be studied, analyzed, and added to our growing catalog of prokaryotic species and strains. Some prokaryotes, however, can't grow in a laboratory setting (at least, not under the conditions scientists have tried). WebProkaryotes reproduce through a cell division process called binary fission. Like mitosis in eukaryotes, this process involves copying the chromosome and separating one cell into two. Binary fission is an asexual form of reproduction, meaning that it does not involve production of eggs and sperm or mixing of genetic material from two individuals.
