Photosynthesis

• Photosynthesis


  The way in which plants make their own food
• Photosynthesis


  Carbon Dioxide + Water

  
• Chlorophyll


  A green pigment that traps light and combines CO2 and H2O to make glucose and O2
• Photosynthesis


  • Makes food (glucose)
  • Stores glucose as starch
• Chemical process


  New substances are formed
• Biological process


  Happens to be in living cells
• Factors affecting Photosynthesis


  • Carbon Dioxide
  • Light
  • Temperature

  
• Experiment to show that starch is made by photosynthesis - needs light
• The glucose that is made is transported in phloem cells
• Glucose can be stored as starch in the leaves OR roots
• Some glucose combines with minerals from the water to make protein (for growth!)
