Eukaryotic and Prokaryotic Cells
Prokaryote = without a nucleus Eukaryote = with a nucleus

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