  • Translocation
    • From source to sink
      • Transportation of organic compounds from source to sink.
      • Active transport
      • Products of photosynthesis are assimilates.
        • Main assimilate is sucrose.
    • Sources
      • Green leaves and stems
      • Storage organs
      • Storage in seeds
    • Sinks
      • Meristems
      • Roots growing mineral ions.
      • Parts laying down food storage- seeds
    • Phloem loading
      • Active process
      • Sucrose is the main
        • Not used in metabolism as readily as glucose and is therefore less likely to be metabolised
