  • Cell structure
    • Endoplasmic Reticulum
      • Structure:
        • Large network of Membranes
          • Types of ER
            • Rough ER: Covered in ribosomes
            • Smooth ER: No ribosomes
      • Function
        • Rough ER- Transports proteins
        • Smooth ER- Produce and transport lipids
    • Golgi Apparatus
      • Structure
        • Stack of flattened membrane bound sacks
        • Small vesicles around it
      • Function
        • 1. Transports and chemically modify substance
        • 2. Produce lysosomes
        • 3. Found inside cells involved in secretion
    • Lysosome
      • Structure
        • Digestive enzymes in a single membrane sack
        • It would destroy the cell is the enzymes got out
          • Acidic (Low PH)
      • Function
        • Breaks down unwanted molecules and structures inside the cell
    • Cell membrane
      • Structure
        • Two layers of phosolipids
        • Receptors on outer surface
      • Function
        • Regulates substance movement
        • organelles have own membrane
    • Nucleus
      • Structure
        • Large round organelle
        • Double membrane (Nuclear envelope)
        • Large nuclear pores for exchange of materials
      • Function
        • Contains cell DNA
        • Controls cell activity
    • Ribosomes
      • Structure
        • Two sub-units
          • One large
          • One small
        • Made of protein and ribosomal RNA
      • Function
        • Site of protein synthesis
    • Mitochondrion
      • Function
        • Aerobic respiration
        • "Power house" of the cell
        • Forms energy in ATP
      • Structure
        • Oval Shape
        • Double Membrane
        • Untitled
