The Archaeal glycerol stoichiometry is different from the Bacteria and Eukarya. This may suggest that: * Archaea use entirely different enzymes for synthesizing phospholipids Archaean membranes are protected from leaking at high temperatures. Archaean membranes can survive extreme temperatures Archean membranes are not weakened by very acidic or alkaline environment The aim of the supergroup system of classification is to: unite the microbial and macroscopic eukaryotes based on phylogenetic infere reflect the differences between the three domain system based on their 16S sequences distinguish the clade of the Prokaryotes from the Eukaryotes show the phylogenetic relationships of the different Eukaryotic groups based molecular data

Archaeal cell structure

Bacteria and archaea are two different prokaryotic domains that, along with eukarya, make up the three domains of life. Archaeal organisms can be found all over the biosphere. Many genera are extremophiles, meaning they thrive in extreme environments such as extremely high temperatures, high salinity, or pH extremes. Bacterial and archaeal cells are characterized by the absence of a nucleus and membrane-bound organelles.
