limiting reactants of photosynthesis – Higher

• What does the law of limiting factors relate to in photosynthesis?

  Light intensity and the rate of photosynthesis
• How do factors interact in the law of limiting factors?

  • Factors do not work in isolation
  • Several factors may interact
  • Any one factor can limit photosynthesis
• What does the graph of carbon dioxide concentration and temperature show regarding photosynthesis?

  They interact with light intensity's effect
• What happens to the rate of photosynthesis as carbon dioxide concentration increases?

  The rate increases until another factor limits
• What effect does increasing temperature have on the rate of photosynthesis?

  The rate increases until another factor limits
• What does the graph showing temperature as a limiting factor illustrate?

  • Effect of temperature at different carbon dioxide concentrations
  • Shows how temperature limits photosynthesis
  • Highlights interaction with carbon dioxide levels
