Scientists classify organisms according to their characteristics. The broadest category of classification is a kingdom. The chart below lists some of the characteristics of each kingdom. The Six Kingdom Classification System Kingdom Eubacteria Archaebacteria Protista Fungi Plantae Animalia Cell Type prokaryotic prokaryotic eukaryotic eukaryotic eukaryotic eukaryotic Cell Wall nearly all all some all all none Cell Number unicellular unicellular unicellular and multicellular unicellular and multicellular multicellular multicellular Nutrition autotrophic and heterotrophic autotrophic and heterotrophic autotrophic and heterotrophic heterotrophic autotrophic and (rarely) heterotrophic heterotrophic Photo- synthetic some some (rarely) some none most (all green plants) none Movement some move with flagella some move with flagella cilia, flagella, or amoeboid do not move do not move muscle organs, cilia, flagella, etc Reproduction asexually by binary fission asexually by fission, budding, or fragmentation varied methods of sexual and asexual reproduction, including binary fission, mitosis, and some meiosis asexually by mitosis (budding, fragmentation, spores) and sexually by meiosis predominantly sexual reproduction by meiosis (cones, seeds, and spores) with some asexual reproduction by mitosis predominantly sexual reproduction by meiosis with some asexual reproduction by mitosis (parthenogenesis) Example Spirilla Methanococci Amoeba Mushroom Sunflower Lion According to the above chart, what is the main difference between the Eubacteria and Archaebacteria kingdoms and the Protista, Fungi, Plantae, and Animalia kingdoms? A. Organisms in the Eubacteria and Archaebacteria kingdoms are autotrophic, whereas all of the organisms in the other kingdoms are heterotrophic. B. Organisms in the Eubacteria and Archaebacteria kingdoms reproduce asexually, whereas all of the organisms in the other kingdoms reproduce sexually. C. Organisms in the Eubacteria and Archaebacteria kingdoms are unicellular, whereas all of the orga
