sap is translocated from areas of supply, called
sources, to areas of metabolism or storage, called sinks. Which of the
following statements about source and sink are TRUE?
a.) Sinks include any nonphotosynthetic organs of the
plant and organs that do not produce enough photosynthetic products to support

storage root is a sink, when it accumulates sugars received from the source
