Green plants and algae use light energy to make their own food. They obtain the raw materials they need to make this food from the air and the soil. The conditions in which plants are grown can be changed to promote growth.

Candidates should use their skills, knowledge and understanding to:

  • interpret data showing how factors affect the rate of photosynthesis
  • evaluate the benefits of artificially manipulating the environment in which plants are grown.
    • Photosynthesis is summarised by the equation:

      carbon dioxide + water - (Light Energy) - Glucose + oxygen

During photosynthesis:

light energy is…
