Lesson Title: Today we are learning about
What factors affect the rate of photosynthesis?
Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding
Success Criteria: You will show your learning by...
  1. Students should be able to explain the effects of temperature, light intensity, carbon dioxide concentration, and the amount of chlorophyll on the rate of photosynthesis.
  2. Students should be able to measure and calculate rates of photosynthesis (MS)
  3. students should be able to extract and interpret graphs of photosynthesis rate involving one limiting factor (MS)
  4. Students should be able to plot and draw appropriate graphs selecting appropriate scale for axes (MS)
  5. Students should be able to translate information between graphical and numeric form. (MS)
  6. (HT only) These factors interact and any one of them may be the factor that limits photosynthesis.
  7. (HT only) Students should be able to explain graphs of photosynthesis rate involving two or three factors and decide which is the limiting factor.
  8. (HT only) Students should understand and use inverse proportion ? the inverse square law and light intensity in the context of photosynthesis.
  9. (HT only) Limiting factors are important in the economics of enhancing the conditions in greenhouses to gain the maximum rate of photosynthesis while still maintaining profit.
  10. * Use data to relate limiting factors to the cost effectiveness of adding heat, light or carbon dioxide to greenhouses.

Keywords:
  • Concentration: the amount of particles in a given space. (1)
  • Collisions: when one particle bumps into another. (1)
  • Limiting factor: something that stops the rate of reaction from increasing past a point. (1)
  • Rate: how fast something occurs. (1)

AFL/Key Questions:
  1. How do each of the following factors affect the rate of photosynthesis: a) temperature, b) light intensity, c) carbon dioxide concentration, d) amount of chlorophyll?
    Increasing temperature increases the rate of photosynthesis to a point as it increases collisions and therefore increases reaction rate. However past a point it starts to evaporate water and slows down photosynthesis. Increasing light intensity increases the rate of photosynthesis to a point where it levels off. Increasing carbon dioxide concentration and the amount of chlorophyll has the same effect as increasing light intensity.
  2. What method can be used to measure and calculate the rate of photosynthesis?
    The rate of photosynthesis can be measured by measuring the amount of oxygen produced over time.
  3. (HT only) What is a limiting factor of photosynthesis?
    (HT only) A limiting factor of photosynthesis is any one of the following components: light intensity, temperature, carbon dioxide concentration, the amount of chlorophyll, that if there is not enough of it will stop the rate of photosynthesis increasing regardless of how much there is of the other components.
  4. (HT) How is the inverse square law important in terms of light intensity in the context of photosynthesis?
    The inverse square law in important as it states that the intensity of light is inversely proportional to the square of the distance from the source.This means that when the light is moved twice as far from the plant it will receive a quarter of the energy.
  5. (HT) How do limiting factors in a greenhouse relate to rate of photosynthesis and profit?
    (HT only) The conditions within a greenhouse can be controlled and therefore can be enhanced to gain the maximum rate of photosynthesis while still maintaining profit.
