When food coloring is added to the water, it travels with the water into the celery's stem and then into the leaves . Plants also absorb nutrients from the soil through the roots and up through the phloem in the plant's stems. The food coloring illustrates how nutrients are delivered to all parts of the plant.
Does celery absorb food coloring?
Why does celery absorb food coloring? Plants need water to survive and they draw water up from their roots through their capillaries. The capillaries are hollow and act a lot like a straw. Adding color to the water helps us visualize this usually invisible process.
What is the purpose of celery experiment?
This experiment allows you and your child to talk about the circulatory system and “capillary” action . The small “vessels” in the celery stalks carry the water and color to the leaves, like the way blood travels through your body.
Why do we cut the celery under water?
This process is called transpiration. That new empty space inside the leaves creates a low pressure , and like a drinking straw, this low pressure allows water below the leaf to travel up the stem. You'll see the little tubes the water travels up when you cut the celery stem, and you can see the colour up in the leaves.

How does celery get water?
Celery is handy for demonstrating capillary action because it has a lot of xylem tubes in the stalk, making for fast water uptake. You'll see the pale green leaves take on a reddish and bluish colour because the dissolved food colouring moves with the water through the xylem tubes into the celery stalk and leaves.
What process caused the water to go up to the celery stalk?
Capillary action occurs when the forces of cohesion and adhesion combine in such a way that they overcome the downward force of gravity, and cause water to move upward through the thin tubes. ... The third activity demonstrates and tracks capillary action in a plant using a celery stalk.
What happens to celery in sugar water?
The adhesion is between the water molecules and the sides of the celery's tubes. The cohesion is between the water molecules and the water molecules themselves. When the force of adhesion is greater than the force of the cohesion, fluids will rise ~ so the liquid will then rise up into the tubes of the celery.
