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

2 Eukaryotic cells Diagram

3 Components Cytoplasm Nucleus Mitochondria Chloroplast Ribosomes RER SER Golgi body Vacuoles

4 Lysosomes Cytoskeleton Centriole Cilium and Flagellum Microvilli Cell membrane Cell Wall Components cont.

5 Prokaryotic cells Diagram

6 Components Cytoplasm Ribosomes Nuclear Zone DNA Plasmid Cell Membrane Mesosome Cell Wall Capsule (or slime layer) Flagellum

7 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
