Archaea differ from the other two domains of lifeâbacteria and eukarya ânot only in their archaea-specific signatures in certain regions of rRNAs, but also in their cell membranes, which are composed of lipids made of ether, unlike bacteria or eukarya whose membrane lipids are made of ester (Gutell et al.
1 Bacteria and eukaryotes have membranes composed mainly of glycerol-ester lipids, whereas archaea have membranes composed of glycerol-ether lipids. 2  The difference is the type of bond that joins the lipids to the glycerol moiety; the two types are shown in yellow in the figure at the right.rchaea are particularly numerous in the oceans, and the archaea in plankton may be one of the most abundant groups of organisms on the planet. Archaea are a major part of Earth's life and may play roles in both the carbon cycle and the nitrogen cycle.
