- - - - faster rate of photosynthesis
    - - Red
        
        some photosynthesis
      - Green
        
        Least photosynthesis
      - Blue
        
        Most photosynthesis
    - - found in palisade layer of the leaf
  - - - Carbon dioxide in, Oxygen out
    - - Product of photosynthesis
  - - - carbon dioxide + water ---> glucose + oxygen
    - - 6(CO2) + 6(H2O) ---> C6H12O6 +6(O2)
- - - - This breaks down the leaf and removes the chlorophyll so there is no pigment left in the case of a colour change
      - Wash leaf in cold water
        
        This softens the leaf some more as the ethanol made it very brittle it also helps to get water into the plant cells so the iodine will diffuse much more easily
        
        Add iodine solution
        
        tests to see whether there is any starch in the leaf
