What is Osmosis?

Osmosis is the passive movement of a solvent, through a semi – permeable membrane, from a region of higher solvent concentration to a region of lower solvent concentration, equalizing the concentrations on both sides....

Osmotic Solution

Osmosis is the movement of molecules from a region of higher concentration to a region of lower concentration through a semipermeable membrane until equilibrium is reached. The Osmotic phenomenon was discovered in 1748 by Nollet. Osmosis is a type of passive transport, that is, it doesn’t require energy from outside and can occur spontaneously. The process occurs naturally in the biological system, such as nutrient uptake in plant roots and maintaining cell turgor pressure....

Effect of Osmosis on Cell

Endosmosis: Endosmosis occurs when the solute concentration inside the cell or system is higher than the surrounding environment, causing water to move inward to equalize the concentration. The cell becomes turgid or shows deplasmolysis. Exosmosis: Exosmosis occurs when the solute concentration inside the cell or system is lower than the surrounding environment, leading to the efflux of water to balance the concentrations. The cell becomes flaccid or shows plasmolysis....

Osmotic Pressure

Osmosis has a direct impact on cells. When a plant or animal cell is surrounded by a hypotonic solution, the animal cell can burst (lyse), while plant cells, with rigid cell walls and a greater need for water, maintain their structure. Animal cells find equilibrium in an isotonic solution, while plant cells lose their turgidity in such conditions....

Difference Between Osmosis and Diffusion

Osmosis (Reverse osmosis): This process employs pressure to drive a solvent through a semipermeable membrane while retaining solutes on one side. It forces pure solvent from an area of high solute concentration through the membrane to an area of low solute concentration, utilizing pressure greater than the osmotic pressure. Reverse osmosis is commonly used for water purification and desalination. Forward Osmosis: Osmosis is utilized to directly separate water from a solution containing undesirable solutes. A draw solution with higher osmotic pressure compared to the feed solution is employed to induce a net flow of water through a semipermeable membrane. This results in the concentration of the feed solution as the draw solution dilutes. The diluted draw solution can be used directly or subjected to a secondary separation process to remove the draw solute, which can be more efficient than using reverse osmosis alone....
