To learn how plants transport water from their roots to their leaves
- Tall clear glass
- Red food coloring
- Celery stalk
Plants need water to grow. Plants transport water from their roots to their leaves through tubes called xylem.
Xylem: tubes that transport water inside plants
Plants need water. Water is transported through the plant through xylem tubes.
How does water get from the roots of a plant to its leaves?
- Gather the necessary materials.
- Fill the glass about halfway with water.
- Add a few drops of food coloring to the water and stir.
- Have an adult cut the bottom of the celery stalk straight across leaving the leaves attached to the stalk.
- Place the celery stalk in the glass, cut end first. Set the glass somewhere where it will not be disturbed overnight.
- The next day, record any changes.
