Unformatted text preview: 9-11-07Chapter 27 ProkaryotesGoals0. Know differences between three domains (Archaea, Bacteria and Eukaryotes) 1. Know 3 main bacterial cell shapes, differences in cell walls2. Give examples of how bacterial organelles are simpler than those in eukaryotes3. Understand the basics of bacterial sex, nutrition and why photosynthesis evolved early4. Know an example of each major bacterial cladeKnow what disease is caused by each bacteria.5. Know why prokaryotes are important to ecosystemsProkaryotes0. Diverse, 5,000 species but up to four million possible1. Some deleterious but most are beneficial 2. Symbionts in eukaryotes, origin of mitochondria and chloroplasts*Symbiotic Organisms3. Two main domains:0. Archaea1. BacteriaBasic Cell Structure6. Unicellular or colonial7. Three main shapes:spheres, rods and helices8. Cell wall of peptidoglycan outside cell membrane9. Cell wall separates bacteria into two functional groups, gram positive and negative10.Double cell wall of gram - bacteria more resistant and pathogenic11.Penicillin breaks down bacterial cell walls (does not affect eukaryotic cells)Figure 27.2The most common shapes of prokaryotes...
