Answer:
Osmosis
Explanation:
Osmosis is the diffusion of water or gas molecules, from a region of higher concentration to a region of lower concentration, through a partially permeable membrane
Diffusion is the net movement of anything from a region of higher concentration to a region of lower concentration.
Plasmolysis is the process of shrinkage or contraction of the protoplasm of a plant cell as a result of loss of water from the cell.
The difference in the concentration of a substance between two areas is called the concentration gradient.
