Question
Water flows up a plant's stem against the force of gravity.
In which of the following ways could the movement of water up a plant be modeled?
A.
Blow through a clear straw in a glass of water. Observe the level of water inside the straw.
B.
Place the tip of a sponge in water dyed with food coloring. Watch how the water moves up the sponge.
C.
Place a clear pipe in a small tub of water. Shake the tub back and forth. Watch how the water moves around the pipe.
D.
Pour a glass of water on top of a towel that is spread out on a table.

To model the movement of water up a plant's stem against the force of gravity, the best option would be:
**B. Place the tip of a sponge in water dyed with food coloring. Watch how the water moves up the sponge.**
This option effectively illustrates capillarity and the process by which water is absorbed and moves upward through a plant's stem and leaves, similar to how water moves through the plant's vascular system (xylem) due to capillary action.
Options A, C, and D don't accurately simulate the specific mechanism by which plants transport water upward against gravity.
**B. Place the tip of a sponge in water dyed with food coloring. Watch how the water moves up the sponge.**
