  • Cells
    • Animal Cell
      • Nucleus
        • Contains DNA in Chromosomes
      • Cell Membrane
        • Structure in the cell
        • Controls what goes in and out
      • Ribosome
        • Where proteins are synthesised
      • Cytoplasm
        • Chemical reactions occur
      • Mitochondria
        • Reactions involving respiration
          • Cells that need a lot of energy have a lot of mitochondria
            • Liver cells - metabolic reactions
            • Muscle cells - Energy to contract
    • Plant Cell
      • Nucleus
        • Contains DNA in Chromosomes
      • Cytoplasm
        • Chemical reactions occur
      • Chloroplasts
        • Where Photosynthesis happens
      • Cell Wall
        • Made of Cellulose
        • Supports the cell
      • Vacuole
        • Contains cell sap which is a weak solution of sugar and salts
      • Cell Membrane
        • Controls what goes in and out of the cell
    • Bacterial Cell
      • Cytoplasm
        • Chemical reactions occur
      • Bacteria do not have Chloroplasts or mitochondria
      • Cell Membrane
        • Controls what goes in and out of the cell
      • Single circular strand of DNA
        • Some contain Plasmids which are smaller strands of DNA in the cytoplasm
      • Cell Wall
        • Made of Cellulose
        • Supports the cell
