Movement of the phloem sap is bidirectional (may be up and down) depending to the location of sink cells. Sucrose enters the phloem from the source cells through the companion cells. Internal pressure differences drive the phloem sap along the sieve tube to sink cells. Water transfers to the xylem by osmosis raising the pressure potential on the sieve tube. Sucrose is unloaded into sink cells increasing the water potential in the sieve tube.
