    • give equation of reaction of photosynthesis
      carbon dioxide + water → glucose + oxygen
    • give chemical equation of photosynthesis
      6CO2 + 6H20 → C6H12O6 + 6O2
    • give uses of glucose from photosynthesis
      respiration, convert to starch for storage, produce fat / oil for storage, produce cellulose for strength and produce amino acids for protein synthesis
    • give factors affecting rate of photosynthesis
      temperature, light intensity, carbon dioxide concentration and amount of chlorophyll
    • describe affect of temperature on rate of photosynthesis
      low - decrease rate - decrease enzyme action
      high - increase rate - increase enzyme action
      too high - stop rate - enzyme denature
    • describe affect of light intensity on rate of photosynthesis
      low - decrease rate
      high - increase rate
    • describe affect of carbon dioxide concentration on rate of reaction
      low - decrease rate
      high - increase rate
    • describe affect of amount of chlorophyll on rate of photosynthesis
      low - decrease rate
      high - increase rate
    • give methods to provide suitable photosynthesis conditions
      greenhouse, artificial light, heaters, carbon dioxide fan, fertilisers and pesticides
