6. Summary of the Differences Between Prokaryotic and Eukaryotic Cells ALBIO9700/2006JK common metabolic pathways huge variety of metabolic pathways reproduction is asexual or sexual reproduction is always asexual cell division is by mitosis or meiosis cell division is by binary fission motility by flexible waving undulipodium, made of tubulin motility by rigid rotating flagellum made of flagellin always has a cytoskeleton, ER present no cytoskeleton, no ER ribosomes are large (80S) ribosomes are small (70S) DNA is linear and associated with proteins to form chromatin, in nucleus DNA is circular, without proteins, in cytoplasm always have nucleus and other membrane-bound organelles no nucleus or any membrane-bound organelles, such as mitochondria often multicellular always unicellular larger cells (> 40 μ m) and 1000-10 000 time the volume small cells (< 5 μ m) Eukaryotic cells Prokaryotic Cells
