PHOTOSYNTHESIS • COMPARING GREEN AND BLUE LIGHT

  • Light is crucial to providing the energy needed for photosynthesis.
  • One method to observe the progress of photosynthesis is to monitor the production of one of its products, oxygen.
  • In this simulation, you will:
    • Assemble a volumeter.
    • Measure the change in the volume of oxygen produced during photosynthesis using a volumeter.
    • Compare rate of photosynthesis in Elodea plants exposed to green or blue light in order to determine if one wavelength of light is better for photosynthesis.
  • Elodea is a plant that lives in water. Photosynthesis will be measured in these plants.
  • The reactants for photosynthesis are provided by sodium bicarbonate solution and light.
  • Sodium bicarbonate (NaHCOX3) solution provides carbon dioxide and water, and light provides the energy needed for photosynthesis.
