The movement of water rather than a solute through a cell membrane is called osmosis.

Here's why:

* Osmosis is the specific process where water moves across a semi-permeable membrane from an area of high water concentration (low solute concentration) to an area of low water concentration (high solute concentration). This movement is driven by the difference in water potential between the two areas.
