Answer:
The Color will transfer from the cup water to the roots and eventually to the petals of white flowers, coloring them.
Explanation:
Inference: Three white flowers are taken and three cups labeling them A,B and C are also taken. Red color is added to A. Blue is added to B and Green is added to C. Mix the color thoroughly in the water and place the flowers in it for five hours.
Plants take nutrients and water from the soil through their roots growing deep in the soil. These roots have tiny hair-like structures called root hairs. They help to absorb water and other necessary nutrients more efficiently. The absorbed water is taken to the root center called Stele. In Stele, their are tiny veins called Xylem. They transfer water to the rest of the parts of plant shoots, flowers, leaves etc.
Observation: Watering flowers with colored water will result in the same process that occurs with the transferring of water and other nutrients from soil to root and to the rest of the plant, subsequently the color will keep on being absorbed by roots/flower-stem with water and taken to Stele and then to Xylem. Resulting in coloring the petals of white flower.
