Worked Solution

Step 1: Recall the parts of the plant transport system: xylem (water-carrying) and phloem (food-carrying). Step 2: Water is absorbed by the roots from the soil. Step 3: The water-carrying tubes transport this water and dissolved mineral salts upwards to the stem and leaves.

Correct answer: They transport water and mineral salts from the roots to all parts of the plant.
