http://ib.bioninja.com.au/higher-level/topic-9-plant-biology/untitled/active-translocation.html WebbThe greater part of this book deals with the physiology and cytology of phloem. The first chapter of the text deals with studies on the definition of the cellular pathways of transport. Chapter 2 considers how the mobility of solutes can be measured and the range of chemical species which are moved in xylem and phloem.

WebbOrganic compounds are transported from sources to sinks via a vascular tube system called the phloem Sugars are principally transported as sucrose (disaccharide), because it is soluble but metabolically inert The nutrient-rich, viscous fluid of the phloem is called plant sap Active Translocation WebbWater potential and transpiration influence how water is transported through the xylem in plants. These processes are regulated by stomatal opening and closing. Photosynthates (mainly sucrose) move from sources to sinks through the plant’s phloem. Sucrose is actively loaded into the sieve-tube elements of the phloem.
