Fish cells, like all cells, have semipermeable membranes. Eventually, the concentration of "stuff" on either side of them will even out. A fish that lives in salt water will have somewhat salty water inside itself. Put it in freshwater, and the freshwater will, through osmosis, enter the fish, causing its cells to swell, and the fish will die. What will happen to a freshwater fish in the ocean?
The fundamental difference between the two is — Osmosis is the movement of the solvent water from a region of higher concentrations to the region of lower concentration through a semipermeable membrane, to maintain the equilibrium. On the other hand, diffusion can be described as the movement of the molecules solid, liquid or gases from the region of higher concentration to the region of lower concentrations, but not through a semipermeable membrane. Both of this kind are the examples of Passive transportation. It is the natural process occurring inside the body and thus promotes the movement of the molecules without a requirement of the energy. The motion can be either through higher to the lower concentration or from lower to the higher concentration, and this difference in concentration of the particles is called concentration gradient. This process is performed to equalize the concentrations gradient on both the side of membrane especially in a case of water solvent.
Osmosis is the result of diffusion across a semipermeable membrane. If two solutions of different concentration are separated by a semipermeable membrane, then the solvent will tend to diffuse across the membrane from the less concentrated to the more concentrated solution. This process is called osmosis. At the cellular level, both processes are types of passive transport. Semipermeable membranes are very thin layers of material that allow small molecules, like oxygen, water, carbon dioxide, ammonia, glucose, amino-acids, etc.
To answer the question, you need to know the definitions of osmosis and diffusion and really understand what they mean. Osmosis : Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. The solvent moves to dilute the concentrated solution and equalize the concentration on both sides of the membrane. Diffusion : Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium. To see an easy demonstration of osmosis, soak gummy candies in water. The gel of the candies acts as a semipermeable membrane.
8.4: Osmosis and Diffusion
Both active and passive transport are the movement of molecules across the cell membrane, or concentration gradient, but there is a key distinction between active and passive transport. Active transport is the movement of molecules against the gradient, while passive transport is the molecular movement with the gradient.
