what are permeable membrane?
they are types of membrane that only allow some types of particles through.
2 of 6
what does isotonic mean?
if the concentration of solutes in the solution outside the cell is the same as the internal concentration, the solution is isotonic to the cell.
3 of 6
what does hypertonic mean?
if the concentration of the solutes in the solution outside the cell is higher than the internal concentration, the solution hypertonic to the cell.
4 of 6
what does hypotonic mean?
if the concentration of the solutes in the solution is lower than the internal concentration, the cell is hypotonic to the cell.

what can cause water to move into or out of the cell by osmosis?
differences in the concentrations of solutions inside and outside a cell cause water to move into or out of the cell.
