Answer: This is the definition and example of Osmosis.
Explanation: Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a region of high concentration of solvent to a less concentration of solvent, thus making the concentrations on each side of the membrane equal.
The cell membrane is also a selectively permeable membrane which allows only certain substances to pass through it. Mostly molecules move from a side where their concentration is high to a side where their concentration is less to make the concentration equal on both sides.
