What do the domains Bacteria and Archaea have in common?

• Both contain eukaryotic cells

• Both contain multicellular organisms

How do the cell walls of bacteria and archaea differ?

• Archaea have cell walls containing peptidoglycan, while bacteria do not

• Bacteria have cell walls containing peptidoglycan, while archaea do not

• Both bacteria and archaea lack cell walls

• Both bacteria and archaea have identical cell walls

What is different about the plasma membranes of archaea compared to bacteria?
