Archaebacteria are a type of prokaryotic unicellular organism with distinctive cell membranes belong to the kingdom âArchaeâ without a cell nucleus. Archae was first classified as a seperate group of prokaryotes in 1977.It is difficult to classify as they have similarities to normal bacteria and larger eukaryotes.rchaebacteria differ from cell wall and cell membrane as it contains a single layer of phospholipid which allows the archaebacteria to live in very limited resource environments. It acts like a parasite which do not harm or help the host.
