Photosynthesis

?

Word Equation = carbon dioxide + water -> oxygen + glucose 

Balanced chemical equation = 6CO2 + 6H2O -> 6O2 + C6H12O6

Limiting factors - variable that is preventing the rate of photosynthesis going faster. 

  • Temperature - If the temperature is higher then enzymes will have more kinetic energy so molecules will react faster but if the temperature is too high enzymes will denature.
  • Light intensity - More light can be trapped by the chlorophyll so the rate of photosynthesis will increase 
  • Carbon Dioxide Concentration - The plant needs to take in CO2 in order for the reaction of photosynthesis to take place.

Maximising growth

Famers can use their knowledge of these limiting factors to increase crop growth in greenhouses. They may use artificial light so that photosynthesis can continue beyond daylight hours, or in a higher-than-normal light intensity. The use of paraffin
