| Diffusion is the movement of particles from a high concentration to a low concentration |

| Osmosis is the movement of water particles across a partially permeable membrane from a high concentration to a low concentration of water. |

| The Solution is ISOTONIC to the cell. | The concentration of solutes in the solution outside the cell is the same as the solution inside the cell. |
| The solution is HYPERTONIC to the cell | The concentration of solutes in the solution outside the cell is higher than the concentration inside the cell. |
| Solution is HYPOTONIC to the cell | The concentration of solutes in the solution outside the cell is lower than the concentration inside the cell. |
| Osmosis is important in living organisms. |

| Active Transport is the movement of molecules from a low concentration to a high concentration through a carrier protein in a cell membrane, this uses energy. | |
| Concentration difference/ gradient Bigger difference=faster diffusion |

| Surface area Increasing surface area= faster diffusion |

|
| Distance over which diffusion occurs Shorter distance= faster diffusion |

| Temperature | The hotter it is the more kinetic energy molecules have so they move faster and diffusion increases |
| Larger organisms need special exchange surfaces because larger organisms have a larger surface area and therefore have a small surface area to volume ratio. |
