  • Cell Structure
    • Organelles Working Together
      • Protein Production
        • Proteins made at ribosom
          • RER make proteins that are excreted or attached to cell membrane
            • New proteins folded and processed in ER
              • Then transported to the Golgi apparatus in vesicles
                • Further Processing
                  • Enter more vesicles to be transported around the cell
          • Free ribosomes make proteins that stay in the cytoplasm
    • Prokaryotic Cells
      • Extremely small cells (tenth the size of eukaryotic cells
      • DNA is circular
      • No nucleus - DNA free in cytoplasm
      • Cell wall made of polsaccharide, but no cellulos or chitin
      • Few organelles, no mitochondria
      • small ribosome
    • Studying Cells - Micropsopes
      • Resolution = how detailed the image is
      • Light Microscope
        • Use Light
        • Lower Resolution : 0.2 micrometres
        • Max magnification is about x 1500
      • Electron Miscroscopes
        • Eclectorons
        • Transmission electron microscope (TEM)
        • Higher resolution
        • Thinner Specimens
    • Eukaryotic Cells and Organelles
      • Eukaryotes
        • Plant Cell
          • Mitochondrian
          • Rough Endoplasmic Reticulum
          • Plasma Membarne
          • Ribosome
          • Cell Wall
          • Chloroplast
          • Vacuole
          • Plasmodesmata
        • Animal Cell
          • Nucleus
            • Nuclear Envelope
            • Nucleolus
            • Plant Cell
              • Mitochondrian
              • Rough Endoplasmic Reticulum
              • Plasma Membarne
              • Ribosome
              • Cell Wall
              • Chloroplast
              • Vacuole
              • Plasmodesmata
          • Smooth Endoplasmic Reticulum
            • Lysosome
              • Golgi Apparatus
                • Cytoplasm
          • I.A.M
