The solute concentration inside a cell is 300 mM and outside it is 30 mM. If the solutes cannot cross the membrane, in which direction do you expect water to move?

Answer 1

Hi Jane.

Osmosis: water moves across the gradient from low concentrations to high concentrations.

Because the solutes can't move, the water does. So in this case, the water would move into the cell, causing it to swell.
