Can you change the color of a flower with food coloring?

Fill a plastic container with water and add a few drops of food coloring. The only way the petals can change color is if the food coloring travels up the stem and goes to the petals. After about one day, the petals of the flower will turn from white to the color of the food coloring.

  • How does water move up a plant?

    1-Water is passively transported into the roots and then into the xylem. 2-The forces of cohesion and adhesion cause the water molecules to form a column in the xylem. 3- Water moves from the xylem into the mesophyll cells, evaporates from their surfaces and leaves the plant by diffusion through the stomata.

Why does a flower absorb color in water?

Most plants “drink” water from the ground through their roots. The water travels up the stem of the plant into the leaves and flowers where it makes food and helps keep the plant rigid. This can happen because water sticks to itself (cohesion) and because the tubes in the plant stem are very tiny.
