| the concentration of dissolved substances in the solution is the same as the concentration of dissolved substances inside the cell | isotonic solution |
| concentration of dissolved substances is lower in the solution outside the cell than the concentration inside the cell | hypotonic solution |
| concentration of dissolved substances outside the cell is higher than the concentration inside the cell | hypertonic solution |
| movement of particles across the membrane that does not require energy | passive transport |
| transport of materials across the membrane using transport proteins | facilitated diffusion |
| movement of materials through a membrane against a concentration gradient | active transport |
