photosynthesis

• Limiting factors of photosynthesis


  • Light intensity
  • Temperature
  • CO2 concentration
  • Chlorophyll concentration
• What factors affects the rate of photosynthesis?


  1)Light

  2) temperature

  3) carbon dioxide concentration
• what is the limiting factor at point A? why?


  light intensity; as the light intensity increases, the rate of photosynthesis increases

  
• What is photosynthesis


  Photosynthesis is an endothermic reaction in which energy is transferred from the environment to the chlorophyll by light
• What is the difference between an endothermic and an exothermic reaction?


  Endothermic: absorbs heat from surroundings Exothermic: releases heat to surroundings
• How do farmers increase carbon dioxide levels in a greenhouse?


  By using a paraffin heater; carbon dioxide is a by-product as it burns
• What are the 5 main ways glucose is used?

  1. respiration
  2. making cellulose
  3. making amino acids
  4. to store as oils/fats
  5. to store as starch
• How to artificially create the ideal farming environment

  by using greenhouses
• is the carbon dioxide concentration still the limiting factor at point B?


  No, as the amount of carbon dioxide increases the rate no longer increases
