Plasmodium which causes malaria when transmitted by mosquitoes) BACTERIA Microscopic Reproduce by Binary Fission Useful and harmful Pathogenic Autrophic and Photosynethsis- bacteria chlorophyll Saprotrophic VIRUSES Sub Microscopic- need electron microscope to see them parasitic- get into a living cell Only reproduce Infect all types of living things e.g. plants,animals, bacteria and dinosaurs Genetic material is DNA in some and RNA in others. E.g. RNA is HIV and DNA is flu 2 of 2
