Question : How do the archae differ from the bacteria ?

Answer»

SOLUTION :Archaebacteria are CHARACTERISED by possessing cell WALLS without peptidoglycan, a substance found in the walls of eubacteria. The LIPIDS in their plasma membrane are branched, differing not only from those of other bacteria but also from all other organisms. The phototrophic FORMS use the pigment bacteriorhodopsininstead of bacteriochlorophyll used by eubacteria.
