| Term | Definition |
|---|---|
| Selective permeable | A property of cell membranes that allows Some substances to pass through while others can not |
| passive transport | The movement of materials through a cell membrane without using energy |
| Diffusion | When molecules move from an area of higher concentration to an area of lower concentration |
| osmosis | Diffusion of water molecules through a selective permeable membrane |
| active transport | Movement of materials through a cell membrane using energy |
| explain how materials move in and out of a cell | Active and passive transport |
| known the different types of membrane transport and how each works | Passive= no energy but active =energy |
| explain the difference between facilitated diffusion And diffusion | Facilitated needs special proteins to help but diffusion naturally does it |
