| Term | Definition |
|---|---|
| Selectively permeable | When some substances can pass through the membrane while others cannot |
| Passive transport | The movement of dissolved materials through a cell membrane without using cellular energy |
| Diffusion | The main method by which small molecules move across the cell membrane |
| Osmosis | The diffusion of water molecules through a selectively permeable membrane |
| Active transport | The movement of materials through a cell membrane using cellular energy |
| Explain how materials move in and out of cells | By diffusion, osmosis, and active transport |
| Know the different types of membrane transport and how it works | Diffusion which moves small molecules across the cell membrane, Osmosis, which is the diffusion of water, And active transport requires the cell to use energy |
| Explain the difference between facilitated diffusion and diffusion | Facilitated diffusion is easier than diffusion |
