Answers will vary. Archaeal membranes have unique membrane-spanning lipids that help them survive in extremes of heat, pH, and salinity and are not composed of petidoglycan. Bacteria and archaeans both have cell membranes but neither have nuclei. Both have ribosomes but lack membrane-bound organelles.
