• What is the word equation for photosynthesis?

  Carbon dioxide + water + sunlight -> glucose + oxygen
• What is the symbol equation for photosynthesis?

  6CO2 + 6H2O -> C6H12O6 + 6O2
• Where does photosynthesis take place?

  • in the chloroplasts - contain pigma
• Where does photosynthesis take place?

  • in the chloroplasts - contain a pigment called chlorophyll that absorbs light
  • endothermic reaction - energy transferred from the environment
• What do plants use glucose for?

  • respiration - transfers energy so plant can convert rest of glucose to other useful substances
  • making cellulose, amino acids
  • stored as oils and fats - turned into lipids for storing in seeds
  • stored as starch - insoluble so better for storing
• What are the limiting factors of photosynthesis?

  • intensity of light, carbon dioxide concentration and temperature
  • chlorophyll - affected by disease or environmental stress
