1. Suppose that xylem were located only in the roots and stems of a plant. Would fluids in the
xylem still move? Explain.

The water won't move if xylem was present only in root and stem of plants.

The xylem is the vascular tissue of the plant that is continuously present from the roots of the plants to the leaves of the plants. These tissues carry the water and mineral salts from the roots to the leaves.

But if the xylem was confined within the roots and stems of the plants, then the water would come upto the stem of plant, but they won't have any tissue that will carry the water from the stem to the leaves. So this will make the plants water deficient. This will kill the plants.
