Although Archaea Although Archaea used to be classified used to be classified as a bacteria, studies as a bacteria, studies of physiology and of physiology and morphology of cell morphology of cell reveals that they are reveals that they are as different from as different from bacteria as we arebacteria as we are they need a separate they need a separate domain.domain.
