The food colouring itself does not have any affect on the growth of the plant, it does however colour or "stain" the tissues of the plant - sometimes making them easier to see under a microscope.
If certain flowers (normally cut flowers) are watered with water containing food colouring, the colour of the flowers can be artificially manipulated (this is sometimes done with chrysanthemums, roses and carnations). The colour change is not permanent as it is not a genetic characteristic, only a physical change due to the coloured pigment.
It effects plants by coloring them but in the after run, it kills them.
Put a flower in a jug of water with a particular color in the bottom, and overtime that flower's petals will be the color of the colored water.
No, but it can change the colour of the flowers - depending on the type of flower and colour of food colouring that it used.
Yes it does the food coloring makes the salt crystals stronger and less likely to dissolve.
Chlorophyll
Food coloring helps the growth of crystals because, the food coloring helps make the crystals stronger and less able to dissolve away.
Its called chlorophyll which is in the plant's chloroplasts.
As plants grow they draw water and nutrients up from the soil. Cut flowers still draw water up from the vase and if there is food coloring in the water it goes up with the water.
No.
No. Food coloring is simply added for visual effect.
no

no
No, food Coloring is a water based dye, it will have a negligible effect on the rate at which water evaporates.
they use this thin called xylem
Yes it does the food coloring makes the salt crystals stronger and less likely to dissolve.
Chlorophyll
Unless the food coloring has some active ingredient, it will not affect the salt water chemically. In the environment, adding excessive food coloring to water may reduce the amount of light available to plants living in the water. Otherwise the coloring itself is innocuous.
No, food coloring will have no effect on the color of the smoke produced by a smoke bomb. That color is produced by chemicals in the smoke bomb mixture that burn, food coloring does not burn.
