Active Translocation

• Translocation


  The movement of organic compounds (e.g. sugars, amino acids) from sources to sinks
• Source


  Where the organic compounds are synthesised - the photosynthetic tissues (leaves)
• Sink


  Where the organic compounds are delivered to for use or storage - includes roots, fruits and seeds
• Translocation of organic compounds


  Transported from sources to sinks via a vascular tube system called the phloem
• Sucrose


  The principal sugar transported, as it is soluble but metabolically inert
• Plant sap


  The nutrient-rich, viscous fluid of the phloem
