The movement of solution, solvent and solute are pass the semipermeable membrane. The osmosis can be explained on the basis of solute and solvent as well.
It is a movement of solute molecule from lower concentration to higher concentration through semipermeable membrane. OR It is a movement of solvent molecule from Higher concentration to lower concentration through semipermeable membrane.
It is a movement of solute molecule from lower concentration to higher concentration through semipermeable membrane. OR It is a movement of solvent molecule from Higher concentration to lower concentration through semipermeable membrane.

Osmosis is flow/movement of water molecules from an area of lower concentrated or dilute solution to an area of higher concentrated solution, across a concentration gradient, through a semipermeable membrane till both areas come to an equilibrium.
It can be defined as from an area of higher water potential to an area of lower water potential, across a water potential gradient.

Please read the below statement carefully.
"Osmosis is the spontaneous net movement of solvent molecules through a partially permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides. ".
Movement of solvent not solution.

Osmosis involves selective permeable membrane b/c semi permeable membrane allows the movement of other molecules in solution through the layers of membrane whereas selective permeable membrane allows movements of only specific molecules through the layers of membrane in any cell.

Osmosis is a type of 'specialised diffusion' which involves the passage of solvent from a region of high solvent concentration to a region of low solvent concentration across the semi-permeable membrane.

Only solvent can pass through semi-permeable membrane, solute cannot. So the flow of solution which is combination of both solute and solvent, is not possible through semi permeable membrane.

Osmosis is one kind of specialized diffusion, that involves the movement of solvent molecules from higher concentration to lower concentration by the help of a semipermeable membrane.

When we talk about osmosis, water molecules passes through a semi-permeable membrane while solutions can pass through a selective permeable membrane.

Its not just water. To be general, its the 'solvent' molecules. If the solvent is water, then we shall talk of water molecules !

Osmosis is the movement of solvent molecules from a lower to a higher reg of concentration through a semi-permeable membrane.
