How is sucrose transported into the phloem
WebSucrose moves down the phloem. Water diffuses from the phloem to the xylem. Water moves via bulk flow from the root into the shoot. For sucrose to be moved from a leaf … WebSucrose is actively transported from source cells into companion cells and then into the sieve-tube elements. This reduces the water potential, which causes water to enter the phloem from the xylem. The resulting positive pressure forces the sucrose-water mixture …
