Document Summary

The basic concept introduced in these modules is that the prokaryotes (kingdom monera) are a very diverse group made up of the eubacteria and the archeabacteria. Explain how each of the following characteristics contributes to the success of prokaryotes: cell wall, capsule, flagella, fimbriae, endospores: Cell wall: maintains cell shape; provides physical protection; prevents cell from bursting in a hypotonic environment; Capsule: enables cell to stick to substrate or to other individuals in a colony; shields pathogens from host"s defensive cells; Flagella: provide motility, enabling cell to respond to chemical or physical signals in the environment that lead to nutrients or other members of their species and away from toxic substances; Fimbriae: allow cells to attach to surfaces, including host cells, or to each other; endospores: withstand harsh conditions. Explain why the prokaryotes, bacterial and archae, are not in the same domain. Bacteria and archaea have many significant differences, which clearly place them in different domains.
