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
their own growth or storage needs
b.) Sources include exporting organs that are capable
of producing photosynthate in excess of their own needs
c.) During the growing season of the first year,
storage root is a sink, when it accumulates sugars received from the source
leaves. During the second growing season the same root becomes a source
d.) Roots, tubers, developing fruits, and immature
leaves, which must import carbohydrate for normal development, are all examples
of sources tissues
Find the correct combination of the source and sink pattern of translocation.
