For the Science topic on Plant systems, we put a celery plant in a beaker of coloured water and left it for 24 hours. This is what we saw the next day. The water in the beaker had reduced by 10ml. Observe the leaves of the plant. From the veins on the leaves, you can clearly see that the red colouring has been transported up the stem to the leaves. This experiment demonstrates that the stem helps to carry water and mineral salts to all parts of the plant.
