Bacteria and Archaea

 Bacteria and archaea are both eukaryotes. They are both vital in nutrient recycling and incredibly small, though small they are important to larger multicellular organisms. both are single celled organisms that lack a nucleus. They have a single piece of circular DNA in the nucleotide area of the cell. they also possess cells surrounded by a cell wall. though they have similarities they also have differences as well. The types of molecules they can system distinguish them. Bacteria have a unique compound called pepitdoglycan in the cell walls. Archaea have unique phospholipids in their plasma membrane and hydrocarbon tails that contain isoprene.
