Bacteria reproduce through binary fission. binary fission is a simpler process than mitosis in plants and animals because bacteria?   are able to produce spores. do not undergo cytokinesis. do not have a nucleus. are single-celled organisms.

This is because bacteria are single-celled organisms.As opposed to animals and plants, which are multicellular organisms, bacteria are not - they consist of one cell only. This is what makes the entire process of binary fission much simpler than mitosis in plants and animals - because of the number of cells these organisms contain.
