10. Tubes for Transporting Food-carrying tubes Phloem Water-carrying tubes Xylem Sugar is produced In the leaves. The food-carrying tubes transport this sugar from the leaves to the other parts of the plant. The root hairs found on the roots Take in water and mineral salts from the soil. The Water-carrying tubes take water from the roots to the other parts of the plant. Take note that the water-carrying tubes are on the inner side & the food-carrying tubes are on the outer side .
11. Tubes for Transporting Food-carrying tubes Phloem Water-carrying tubes Xylem Note the arrows for the water & food carrying tubes and the direction they travel.
12. In this picture, the food-carrying tubes are cut. So, this plant is NOT able to transport food from the leaves to the other parts of the plant. But the water-carrying tubes which are on the inner part of the stem are NOT CUT. So this plant is still able to transport water from the roots to the other parts.
13. These flowers shown above did not receive these colours naturally. Can you explain how they got these colours now that you are aware of the water-carrying tubes in stems?
14. This experiment is exciting. Look at Celery stalk that has been divided into two parts. Each part is put in different colours. after about 1 day, you’ll notice that the water carrying tubes in each half will be different in colour – according to the colour of water they were put in. Each celery is put into different coloured water. after a day, take out the celery stalks and cut across the stem. You will notice that the water-carrying tubes in each will have the colour of water that the stem was put in. Try this experiment!

Editor's Notes
NOTE: Transport system in plants. Xylem: Runs from roots to other parts of plants. Function: Transports water and minerals. Supports the plant Phloem: Runs from leaves to other parts of plants. Function: To transport food.
