list the characteristics of prokaryotes an organism with cells lacking a true nucleus and membrane-bound organelles
list the similarities between prokaryotes and eukaryotes cytoplasm, has genetic material, ribosomes, both function to carry out life processes
list the differences between prokaryotes and eukaryotes prokaryotes: unicellular, smaller and simpler, no nucleus, nucleoid Eukaryotes: contains few unicellular but is mostly multicellular organisms, larger and more complex, has a nucleus membrane- bound organelles
