Final answer:
The solvent in osmosis moves from a diluted solution to a concentrated solution through a semipermeable membrane until equilibrium is achieved, driven by osmotic pressure.
Step-by-step explanation:
During osmosis, the solvent is moving from a diluted solution (high solvent concentration) to a concentrated solution (low solvent concentration).
Osmosis is a process by which solvent molecules pass through a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration. This movement continues until the solute concentrations on both sides of the membrane are equal. It's important to note that this is a passive process, occurring without the input of external energy. Osmotic pressure is the driving force of this movement, representing the pressure which needs to be applied to a solution to prevent the inward flow of water across the semipermeable membrane.
