Osmosis is a biological and physical process that involves the spontaneous movement of solvent molecules (usually water) across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration. The goal of osmosis is to equalize the solute concentration on both sides of the membrane.

In simpler terms, osmosis can be defined as the movement of water from a region where there is more water (lower solute concentration) to a region where there is less water (higher solute concentration) through a selectively permeable membrane.

Osmosis is driven by the natural tendency of water molecules to move from an area of higher concentration (dilute solution) to an area of lower concentration (concentrated solution) in order to balance the concentrations on both sides of the membrane. The selectively permeable membrane allows water to pass through but restricts the movement of solute particles.

Osmosis plays a crucial role in various biological processes, such as the absorption of water by plant roots, the regulation of water content in animal cells, and the movement of fluids within living organisms. It also has practical applications, including water purification, preservation of food, and in medical contexts such as kidney function and dialysis.
