Red blood cells placed in a solution with the same water concentration as their cytoplasm (0.85 per cent salt solution) will not experience an overall change in volume. No osmosis occurs.

The slideshow shows an example of osmosis showing the direction of movement of water between two different concentrations of sugar solutions. In pure water, the cell contents (the cytoplasm and ...
