Fig. 37. — The region in which water and solutes enter the plant body. They move through the cells of the cortex by osmosis. These cells are alive. The cells of the xylem are dead. When the water and solutes enter the xylem they move in a mass together, not by osmosis. with the water just as sugar dissolved in tea would move with the tea if you poured it from the cup. But before reaching the wood, that is between the root-hairs and the wood cells, the water and the solutes have to move through the living cells of the cortex, and through these they move by osmosis, and not together as one mass. Now it appears that the sap current, ascending through the wood cells, carries away solutes from the cells of the cortex which border it. Then, to satisfy the laws of.
