Summary of differences Prokaryotic CellsEukaryotic cells small cells (< 5 mm)larger cells (> 10 mm) always unicellularoften multicellular no nucleus or any membrane-bound organelles always have nucleus and other membrane-bound organelles DNA is circular, without proteinsDNA is linear and associated with proteins to form chromatin ribosomes are small (70S)ribosomes are large (80S) no cytoskeletonalways has a cytoskeleton cell division is by binary fissioncell division is by mitosis or meiosis reproduction is always asexualreproduction is asexual or sexual
