    : Prokaryotes "have" (some have) peptidoglycan cell walls, capsules, organelles for motility (like cilia and flagella) and 70S ribosomes made of 30S and 50S subunits. (Eukaryotes have no capsules, no organelles for motility, the ones with cell walls have cell walls made of cellulose, and they have 80S ribosomes with 40S & 60S subunits.) When you think of eukaryotes, think of human cells and plant cells (just as two examples); they're more advanced and evolved than prokaryotes, and have all of the organelles which prokaryotes lack. Some eukaryotes (human cells, for example) have only a plasma membrane, while others (plant cells) have a cell wall made of cellulose. Biologists believe that the mitochondria in many eukaryotes evolved because ancient prokaryotes enveloped other prokaryotes capable of creating large amounts of ATP from aerobic respiration, and these became modern-day mitochondria! Cool. Prokaryotes were definately here first, and though they lack a nucleus, they do have plasma membranes, and some have cell walls made of peptidoglycan- some even have capsules. When you think of prokaryotes, think bacteria, like E. coli. As mentioned before, many have organelles like cilia or flagellum for motility. They do have ribosomes for protein production, though prokaryotic ribosomes are smaller than eukaryotic ribosomes. Prokaryotes do not, however, have any *membrane-bound* organelles, unlike eukaryotes. And in case you're wondering, no, ribosomes are not considered mb-bound organelles, they are made of RNA and are free-floating in the cytosol.

    Eukaryotes have cytoskeletal structures but prokaryotes do not have. prokaryotes do not have a true nucleus but eukaryotes have. eukaryotes divide by mitosis but prokaryotes divide by simple fission. eukaryotes have membrane bound organelles but prokaryotes do not have
