Andrew Platt Bio lab @ 3:30 on Tuesdays General Biology I Laboratory Nine Bacteria & Protista Pre-Lab Questions 1. List and describe four ways that Archaea and Bacteria differ from each other in terms of structure and genetic composition. Plasma Membrane All prokaryotes have plasma membranes with a fluid mosaic architecture. The plasma membranes of archaea differ from both bacteria and eukaryotes. Archaean membrane lipids are composed of glycerol linked to hydrocarbon chains by ether linkages, not the ester linkages seen in bacteria and eukaryotes. These hydrocarbons may also be branched, and they may be organized as tetraethers that form a monolayer instead of a bilayer. Cell Wall Despite similarities, bacteria and archaea differ fundamentally Archaea and bacteria are similar in that both have a prokaryotic cellular structure, but they vary considerably at the biochemical and molecular levels. They differ in four key areas: plasma membranes, cell walls, DNA replication, and gene
