Answer the following questions:

What happens when an empty potato cup is kept in a trough with water? Why?

Water gets collected in the hollow cup. As a result of osmosis, water enters inside. Since the medium surrounding the potato cup has a higher concentration of water than the potato, the water molecules move in. The water molecules move along the concentration gradient from a region of higher concentration to a region of lower concentration.
