  1. Bacteria - Eubacteria Domain Prokarya

  2. Plantae Monera Bacteria-Eubacteria Lumpers Splitters Shifting Kingdoms

  3. Multicellular Animals Archezoans Euglenoids Slime Molds Archaebacteria Brown Algae Protozoans Chrysophytes Red algae Green Algae Bryophytes Myxozoans True Fungi Tracheophytes Bacteria 8 5 3 2 1 Extant How Many Kingdoms? Extinct Long Time with Prokaryotes only Original Cell

  4. Bacteria - Eubacteria • Ancient fossils 3.5 billion years b.p. • Archetype for prokaryotic organisms • Phototrophs • Chemoautotrophs • Heterotrophs • Saprobes • Parasites (bacteria benefit, host harmed) • Commensals (bacteria benefit, host unharmed) • Mutualists (bacteria and host both benefit) • Unicellular, colonial, filamentous • Bacillus, coccus, spirillum

  7. Domain Prokarya Proteobacteria Gram-negative photoauto-, chemoauto-, hetero-trophs   symbionts, parasites Rhizobium-legumes: N2 fixation Agrobacterium-host: Recombinant DNA Rickettsias: Rocky Mountain Fever likely source of mitochondrion by endosymbiosis Kingdom Bacteria Universal Ancestor

  8. Domain Prokarya Proteobacteria Gram-negative photoauto-, chemoauto-, hetero-trophs    nutritionally diverse Nitrosomonas in soil: NH4+ NO2- ammonium nitrite Kingdom Bacteria Universal Ancestor

  9. Domain Prokarya Proteobacteria Gram-negative photoauto-, chemoauto-, hetero-trophs     Photosynthetic: Chromatium CO2 + H2S CH2O + S(solid) Heterotrophic: Legionella-Legionnaires’ disease Enterics: Escherichia coli in your intestine Salmonella food poisoning Vibrio cholerae cholera Kingdom Bacteria Universal Ancestor

  10. Domain Prokarya Proteobacteria Gram-negative photoauto-, chemoauto-, hetero-trophs      Myxobacteria: slime secretion, aggregation, spores Bdellovibrios: rapid locomotion 100m/sec penetrate prey bacteria 100 rps Kingdom Bacteria Universal Ancestor
