  • Cells and Organelles
    • Eukaryotic
      • Nucleus
        • nuclear envelope
        • Nuclear pore
      • Lysosome
        • digestive enzymes
      • Rough ER
        • ribosomes- folds + processes proteins
      • Smooth ER
        • no ribosomes- synthesises+ processes lipids
      • Golgi Apparatus
        • processes + packages new lipids and proteins
        • makes lysosomes
      • Mitochondria
        • double membrane- Cristae/Matrix
        • site of aerobic respiration- ATP.
      • Chloroplast
        • double membrane. Thylakoid membranes- grana.
        • site of photosynthesis
      • Cilia
        • 9+2 formation
        • move substances along cell surface
      • Flagellum
        • microtubules contract to move- outward motors
    • Protein Production
      • ribosomes on RER produce proteins in vesicles
      • Proteins enter more vesicles and move out cell surface- secreted.
    • Cytoskeleton
      • microfilaments/microtubules
      • Support/ strengthen/ movement of materials/ cause cell to move
    • Prokaryotic
      • Circular DNA
      • No nucleus
      • cell wall made of polysaccharide
      • Flagella in helix
      • 70s ribosomes
