The Movement of Organic Compounds Throughout Plants is Described as ____

Question

The movement of organic compounds throughout plants is described as ____.  
A) cohesion-tension
B) source-to-sink
C) facilitated transport
D) active transport
E) transpiration pull

Accepted Answer

The movement of organic compounds throughout plants is described as source-to-sink. This refers to the movement of sugars and other compounds from where they are synthesized (source) to where they are used or stored (sink). This can occur via phloem transport, which is a specialized type of transport that requires energy and can occur bidirectionally.
