  • 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
