which process does osmosis involve?
movement of water across a cell membrane
movement of water up a concentration gradient
movement of solute up a concentration gradient
movement of solute across the cell membrane

Explanation:

Osmosis is defined as the passive movement of water molecules across a selectively permeable membrane (like a cell membrane) from an area of lower solute concentration to higher solute concentration (down the water concentration gradient). The key elements are water movement and a membrane.
