I'm taking Biology in college right now...this is what I gather.
Dye in the water doesn't harm the plant (in most cases). the water is absorbed through the roots of the plant, which travel to the leaves/petals, there they are then evaporated while producing energy process of photosynthesis...water is attracted to each other -aka cohension, water molecules are attracted to each other b/c of positive and negative ions. All being said, the water evaporates while the dye remains in the plant.
Typically, dark colored food coloring, such as red or blue, will color a white flower the quickest due to their intensity and concentration. It is recommended to dilute the food coloring in water before placing the flower in the colored water to prevent damage to the flower.
No. Colored sodas do not change the color of a white flower. Any soda can makes the flower die because sodas have acid and sugar which can make a flower die.
Dunk it in molten wax before you put it in the blue water.
Some flowers use more water, faster. The faster it would normally use water, the faster it would absorb a liquid dye.
I know that if you put freshly cut white chrysanthemums in water that has food coloring in it, the color will come up through the veins of the flower.
The reason if you do that is because, flowers have itty bitty tubes in their stems that suck all the nutrients out of the ground helping it grow, if the water is is colored then the flower will suck up the colored water feed it the water then the flower will be that color. If I were I would test it on celery first to see if it works. The reason why I'm telling you to test it first on celery is because thy also have itty bitty tubes! from, ilovejonasbrothers
Greece's national flower is the Bear's breech (Acanthus Mollis), it has long white and violet or rose colored blooms.
Cut flowers are still able to absorb water when placed in a vase as long as the xylem and phloem vessels are open and not clogged/ blocked by dead plant tissue and debris. Any dye that is placed in the water will be absorbed up through the stem and move through the plant tissue (translocation) where it will collect or be deposited. This dye coloring is then visible in the flower when we look at it; sometimes the entire flower can become colored, sometimes only portions colored - especially if some of the xylem vessels are damaged or blocked and no water is transported through them. White flowers are normally used to colour artificially as the dye coloring does not always show clearly against darker colored coloured flowers (i.e. those that have a naturally darker coloring)
It can be done by splitting the stem in the middle about 6 inches up the length, then placing the two halves in separate dyed glasses of water, it will take up the colored liquid and change to the color of the water. Should be done with a white flower.
Flowering plants have vascular systems which consist of xylem and phloem. The xylem transport water and minerals from the roots all the way to the leaves until the water is released through the stomata, openings of the leaves. So allowing plants to intake colored water the plant will turn the color of the water because of water transport through the xylem. The water will absorb into the roots travel up the stem and leave through the stomata in the flower petals, dying the plant the color of the water as the water exits the plant.
Normally, you can't. However, a white flower can be picked and put in a glass with food coloring and water.. In a few days, the flower will be the same color as the food coloring and water. Otherwise, paint the flower?
This phenomenon is caused by the flower "drinking" the water and placing the hydration in the petal. When the flower drinks the water, it spreads the water throughout the plant. Because the petals are white, the red water shows up very well.
