Chapter 1 Lesson 4
| Term | Definition |
|---|---|
| Selectively permeable | Is a type of synthetic or biologic, polymeric membrane that allows certain molecules or ions to pass through it by osmosis |
| Passive transport | Is a type of membrane transport that does not require energy to move substances across cell membranes |
| Diffusion | The spreading of something more widely. |
| Osmosis | A process by which molecules of a solvent, Tinder passed through semipermeable membrane for my last concentrated solution to more concentrated one. |
| Active transport | Remover of iron molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy. |
| Explain how materials move in and out of cells | Diffusion osmosis, facilitated diffusion and active transport. |
| Know the different types of membrane transport | The three primary types of membrane transport are simple diffusion facilitated, diffusion and active transport. |
| Explain the difference between facilitated diffusion and diffusion. | The main difference between diffusion and facilitated diffusion is that diffusion is a passive process that allows small molecules to travel across the membrane, well facilitated diffusion allows, both small and larger molecules to pass to the membrane. |
