Vedclass · Answer

(C) Vein loading (or phloem loading) is the process by which sugars (sucrose) are transported from the mesophyll cells into the sieve tube elements of the phloem. $1$. Sucrose is actively transported into the companion cells and then into the sieve tube elements. $2$. This high concentration of sugar in the phloem creates a hypertonic environment,causing water to move from the adjacent xylem vessels into the phloem by osmosis. $3$. Therefore,both the movement of food into the sieve tubes and the subsequent movement of water from the xylem are integral parts of the pressure-flow hypothesis mechanism.
