| Term | Definition |
|---|---|
| Selectively permeable | property of cell membrane that allows some substances to pass through while others connect |
| passive transport | movement of materials through a cell membrane without using energy |
| diffusion | The process by which molecules move from an area of higher concentration to an area of lower concentration |
| osmosis | The diffusion of water molecules through a selectivity Premable membrane |
| Active transport | The movement of materials through a cell membrane using cell energy |
| explain how materials move in and out of cells | membrane move in and move out of the cell |
| Know the different types of membrane transport and how each works | It works by passive, which does not use any energy and it changes the difference cells |
| explain the difference between facilitated diffusion and diffusion | Diffusion is the main method by which small molecules move across the cell membrane. It is a helping diffusion not just a normal delusion. |
