To make it look more appealing to the eye so as to want to eat it more. EX: You probably wouldn't want to eat a mold looking substance even if it tasted like heaven?
Thats my best guess.
well food coloring actually colors your food. for example, if you want green mashed potatoes, you put a few drops of food dye in the mashed potatoes. it really does brighten your food! :)
It's usually added as decoration e.g. adding food colouring to icing for a cake could make it go from any colour from green to pink!!!
All legal food colourings have no biological action except in extremely high doses (far beyond anything that could be obtained by eating or drinking a product containing them).
It changes the colouring of the plant
Chlorophyll
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.
yes it is bad
Physical, the water is still water and the food coloring is still food coloring you just mixed them together in one space. If you waited long enough the food coloring and water would settle back out so you had just water and food coloring.
No.
photosynthesis
cacti
they use this thin called xylem
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.
yes it does! It uses something called capilarry action
no there is not DNA in food coloring
Its called chlorophyll which is in the plant's chloroplasts.
You take food coloring and add it to the plants water it will change the color
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.
chlorophyll is the green coloring plants use in photosynthesis
