Page 9BacteriaMembers of the kingdom Monera are microscopic organisms that include the bacteria and cyanobacteria. Both the bacteria and cyanobacteria are prokaryotes. Prokaryotes lack a nucleus, and they have no organelles except ribosomes. The hereditary material exists as a single loop of double-stranded DNA in a nuclear region, or nucleoid. Members of the kingdom multiply by an asexual process called binary fission. No evidence of mitosis is apparent in the reproductive process. Bacteria live in virtually all the environments on earth, including the soil, water, and air. They have existed for approximately 3 billion years, and they have evolved into every conceivable ecological niche on, above, and below the surface of the earth.Characteristics of bacteriaMost bacterial species are heterotrophic, that is, they acquire their food from organic matter. The largest numbers of bacteria are saprobic, meaning that they feed on dead or decaying organic matter. A few bacterial species are parasitic. These bacteria live within host organisms and cause disease. Certain bacteria are autotrophic, that is, they synthesize their own foods. Such bacteria often engage in the process of phot
