5.5 Uptake of water and minerals in the roots - Siyavula

Most water travels either in, or between the cell walls (of the parenchyma cells) by simple diffusion. The water must pass through the endodermis to enter the xylem. Once water is in the xylem of the root, it will pass up the xylem of the stem. Figure 5.27: Step-by-step transport of water in plants, from the roots to the xylem.

#62 Passage of water through root, stem and leaf

There are no cross-wall and no living contents so the water and mineral salts can pass through freely. Describe the mechanism of water movement through the xylem. Water moves by the pull from the leaves caused by the transpiration. Xylem vessels are very thin, so they act like a capillary tube helping to withdraw water upward. 1.
