Document Summary

Outcomes: create a table comparing the three domains (how do cell walls, cell structures, and flagella differ?, what basic features do all bacteria possess, what does gram stain tell us about bacteria. Id gram + and gram : cc the ways that genetic diversity arises in the bacteria. Compare these to eukaryotic mechanisms (where does eukaryotic diversity come from?: compare/contrast transformation, transduction, and conjugation, (and mutation. , co compare the two major groups of bacteria to each other, nowhere mitochondria/chloroplasts come from. Enzymes for respiration and photosynthesis in plasma membrane. Bacteria only - peptidoglycan in cell wall. 2 step process stin wash to id bacteria: Does not hold violet, outer membrane of lipopolysaccharides (lps: motility. Taxis = movement (+ vs - taxis) Found in all domains but analogous (convergent evolution) Factors promoting genetic diversity: rapid reproduction & mutation. Two factors give rise to high levels of genetic diversity. 1 in 10 million chance: genetic recombination.
