What structures must be present in a cell for osmosis to take place?

For osmosis to occur in a cell, a selectively permeable membrane is needed to allow the passage of water molecules. The presence of a concentration gradient across the membrane, with different concentrations of solutes inside and outside the cell, is also required to drive the movement of water molecules. Additionally, the cell must have a higher concentration of solutes than the surrounding environment to create a driving force for water to move into or out of the cell.
