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 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.

This was a very helpful question. Thanks all.

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

Actually, osmosis is a region of higher water potential to the region of lower water potential.

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.

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

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.

It is not the solution that moves.
It is the solvent particles that moves in osmosis.

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.
