According to the pressure flow hypothesis of phloem transport,
A) solute moves from a high concentration in the source to a lower concentration in the sink.
B) water is actively transported into the source region of the phloem to create the turgor pressure needed.
C) the combination of a high turgor pressure in the source and transpiration water loss from the sink moves solutes through phloem conduits.
D) the formation of starch from sugar in the sink increases the osmotic concentration.
E) the pressure in the phloem of a root is normally greater than the pressure in the phloem of a leaf.
