prokaryotes
lack a nucleus
DNA is less structured and shaped like a loop
unicellular
organelles: cell wall, cytoplasm, flagella and pili, nucleoids, plasmids
examples: bacteria, archaea

made up of cells with membrane-enclosed organelles
DNA is bound in the nucleus
unicellular or multicellular
examples: animals, protists, plants, fungi
DNA is organized into chromosomes
genus
