pigment
coloring dye
it is used as coloring dye.
maybe it is the chlorophyll
coloring dye
The xylem tubes, tubes that suck up water and minerals in a plant, in the celery plant suck up the food coloring which to the tubes, is water. The tubes then just spread the water/food coloring to other parts of the celery.
Well, the flower will change the color of the food coloring. For example, if you used red the flower would change red. Unless, you put it ON the plant then it would die! You would have to put the food dye/coloring in the plant's water to help it survive when the coloring reaches its roots.
My best guess is celery contains celery! It is a fibrous plant with green coloring and whitish coloring on inner surfaces.
it only takes about 1 day
the sun absorbs the colour when it beams down
There are many products used as food coloring. Some are natural. They extracted from plant materials, from animals and some even come from insects farmed for that purpose. Food coloring is also made artificially in a factory from chemicals.
Depends on the plant. White dasies will change color very quickly.
Plants primarily absorb light through chlorophyll, but they can also absorb certain wavelengths of light reflected by pigments such as red food coloring. However, when red food coloring is added to water, it can be absorbed by the plant's roots and transported through the plant's vascular system, potentially affecting the color of the leaves or flowers. Generally, the impact of red food coloring on plant health is minimal, as it does not provide any nutritional value or harm the plant in typical concentrations used for experiments.
