Worked Solution
Step 1: The water in the beaker was coloured red.
Step 2: The red colour reached the petals, meaning the water was transported upwards.
Step 3: The water-carrying tubes (xylem) transport water and mineral salts from the roots to all parts of the plant.
Correct answer: The water-carrying tubes.
