In which of the following ways could the movement of water up a plant be modeled?

Question

A.
Pour a glass of water on top of a towel that is spread out on a table.
B.
Place the tip of a sponge in water dyed with food coloring. Watch how the water moves up the sponge.
C.
Blow through a clear straw in a glass of water. Observe the level of water inside the straw.
D.
Place a clear pipe in a small tub of water. Shake the tub back and forth. Watch how the water moves around the pipe.

Answer 1

The movement of water up a plant can be best modeled by:

B. Place the tip of a sponge in water dyed with food coloring. Watch how the water moves up the sponge.

This option effectively demonstrates capillary action, which is the process that helps water travel through the small tubes (xylem) in a plant. The sponge acts similarly to plant tissues, allowing you to observe how water moves upward through it.
