WebThe plasma membrane—the outer boundary of the cell—is the bag, and the cytoplasm is the goo. Of course, a cell is ever so much more than just a bag of goo. It's a complex, highly organized unit, the basic building block … WebRecall that the general structure of a cell membrane is a phospholipid bilayer composed of two layers of lipid molecules. In archaeal cell membranes, isoprene (phytanyl) chains linked to glycerol replace the fatty acids linked to glycerol in bacterial membranes. Some archaeal membranes are lipid monolayers instead of bilayers (Figure 7). cst pool
