Answer:
Have you ever heard someone say, "That plant is thirsty," or "Give that plant a drink of water."? We know that all plants need water to survive, even bouquets of cut flowers and plants living in deserts. But have you ever thought about how water moves within the plant? In this activity, you'll put carnations in dyed water to figure out where the water goes. Where do you think the dyed water will travel, and what will this tell you about how the water moves in the cut flowers?

Answer
There will be a change of color likely to appear in the stem and leaves of the plants.
Explanation:
- Xylem is a tissue made up of thin tubes located below the surface of the plant's stem.
- Through capillary action water molecules from the soils are attracted by the stem to pull upwards.
- There are two types of absorption one is active and the other is passive absorption. Passive absorption happens by transpiration pull and active absorption happens through the action of roots.
- Root absorbs the black dye water to enter the stele. This makes the changes in the color of the stem.
