Osmosis is the movement of water across a semi-permeable membrane the process by which osmosis occurs is when water molecules diffuse across a cell membrane from an area of higher concentration to an area of lower concentration. It is not necessary for one of the liquids to be pure water in order for osmosis to occur all that is necessary is for the concentrations on the two sides of the membrane to be different isotonic solutions.

Osmosis may occur when there is a partiallypermeable membrane, such as a cellmembranewhen a cell is submerged in water, the watermolecules pass through the ce. Osmosis and dialysis are of prime importance in living organisms, where they influence the distribution of nutrients and the release of metabolic waste products living cells of both plants and animals are enclosed by a semipermeable membrane called the cell membrane, which regulates the flow of. But while knowing that reverse osmosis can convert seawater to drinking water is useful, what we really need to understand is how the heck the process occurs assuming that you have a fairly good grasp on the definition of reverse, we better start by taking a look at how osmosis works before we put the two together. It occurs when two solutions are separated by a partially permeable membrane the definition of osmosis is as follows: osmosis is the movement of water molecules from an area of high water concentration (weak/dilute solution) to an area of low water concentration (strong/concentrated solution) through a partially permeable membrane.

Osmosis is a special example of diffusion it is the diffusion of a substance through a semipermeable membrane from a more dilute solution to a more concentrated solution this process is also passive since no external energy is needed. Osmosis does not occur in an isotonic solution a hypotonic solution is a solution in which the concentration of dissolved substances is lower than the concentration inside the cell if a cell were put in a hypotonic solution, osmosis will cause water to move through the cell membrane into the cell.
