During osmosis Group of answer choices pure solvent and a solution both diffuse at the same time through a membrane.

During osmosis A) pure solvent diffuses through a membrane but solutes do not. B) pure solutes diffuse through a membrane but solvent does not. C) pure solvent and a solution both diffuse at the same time through a membrane. D) gases diffuse through a membrane into a solution and build up pressure.

Explanation:A.

The net movements of solvent from the region of higher water potential (solvent) to a region of lower water potential(solute) through  a semipermeable membrane is called osmosis. It is a peocess where the solute dissolved in the solvent and the resulting solution pass the selective permeable membrane,A selective permeable is  the type which allows water,gases, and  non polar molecules to pass through, but restrict polar and other large molecules  through its walls.

Generally during osmosis,the water molecules and solute molecules interacts.These interaction ,due to dipole dipole effects of the water molecules, reduced the pressure of water on the solute in solution .Consequently, the water molecule of the pure water (the  solvent )exerts more pressure on the weaker solution i,e higher water potential

Hence,this pressure forces water molecules across the semi permeable membrane,from higher water potential to lower water potential.It is the major biological process of plants and animals.
