  • Cell Organelles
  • carry out many of the metabolic tasks important to living things
  • are small membrane-bound structures
  • plays an important role in:
    • producing more cells
    • generating energy
    • building new molecules
  • prokaryotic cells
    • example : bacteria
    • have no membrane bound organelles or nucleus
    • contain:
      • DNA
      • Ctytoplasm
      • cell membrane
      • cell wall
  • nucleolus
    • where RNA is produced in the nucleus
  • ribosomes
    • site of protein synthesis
    • found on the rough endoplasmic reticulum
      • vesicles
        • protect proteins when they leave a cell tot travel
  • toxins
    • changed into less harmful substances on the smooth ER
      • by detoxification
  • plant organelles
    • central vacuole
      • store water, ions + wastes
      • makes the plant rigid when its full
    • cell wall
    • chloroplasts
      • site of photosynthesis
  • site of photosynthesis
