Final answer:
When you water your wilting plant, the water moves from an area of higher water concentration to an area of lower concentration through osmosis.
Step-by-step explanation:
Osmosis is the diffusion of water molecules across a selectively permeable membrane from an area of higher concentration to an area of lower concentration. In this situation, when your favorite plant is wilting, the soil is very dry, which means it has a low concentration of water.
When you water the plant, the water moves from the area with a higher concentration of water (outside the roots) to the area with a lower concentration of water (inside the roots). This happens through osmosis, which is the movement of water through a semipermeable membrane to reach equilibrium.
