Osmosis occurs until the concentration gradient of water goes to zero or until the hydrostatic pressure of the water balances the osmotic pressure. Osmosis occurs when there is a concentration gradient of a solute within a solution, but the membrane does not allow diffusion of the solute.

Osmosis is the diffusion of water through a semipermeable membrane according to the concentration gradient of water across the membrane. Whereas diffusion transports material across membranes and within cells, osmosis transports only water across a membrane and the membrane limits the diffusion of solutes in the water.

Diffusion and osmosis represent the movement of substances (water in the case of osmosis) from an area of high to low concentration, down a concentration gradient. They are passive, and do not require energy. As it’s name suggests, it is an active process, requiring energy.

Osmosis is the net movement of water across a selectively permeable membrane driven by a difference in solute concentrations on the two sides of the membrane. A selectively permiable membrane is one that allows unrestricted passage of water, but not solute molecules or ions.

(1) Formula for “osmotic force”: F=PS’ or F=PS(1-[Ci]k) where F is “osmotic force”; P is the pressure on the membrane; S’ is the osmotic effective membrane area; S is membrane total area; [Ci] is the molar concentration of the solute i in solution; k is the equilibrium constant, being the fraction of the ineffective …

Osmosis is the movement of water from a less concentrated solution to a more concentrated solution through a partially permeable membrane. The important thing to remember is that osmosis is the movement of WATER ( or other solvent ) not the particles dissolved in the water.

If water is withheld from a flowering plant, the flowers wilt. If bacterial cells are placed in concentrated salt water solution, they collapse and die. Human red blood cells placed in fresh water expand and burst. These are examples of the effects of osmosis, the process by which water passes through a cell membrane.

Osmosis has a number of life-preserving functions: it assists plants in receiving water, it helps in the preservation of fruit and meat, and is even used in kidney dialysis. In addition, osmosis can be reversed to remove salt and other impurities from water.

Answer: conditions required for osmosis are: presence of a concentration gradient ,the solution separated by a semi permieable membrane should have different concentration. presence of a semi permeable membrane.
