RLO: Concentration Gradients
Resources
| Title/link | Description |
|---|---|
| Osmosis & Diffusion (RLO) | Explaining the difference between the processes of diffusion and osmosis, and introducing the concepts of concentration gradients and tonicity. |
| The Cell: Passive Transport Diffusion | A short learning object hosted at the Wisconsin Online Resource Center, which outlines the process of passive transport in biological cells. The Wisconsin repository holds many other learning objects relating to biological science and nursing which are worth exploring. |
Glossary
- Diffusion: the movement of molecules across a concentration gradient until an equilibrium concentration is reached.
- Osmosis: the movement of molecules across a semi-permeable membrane, which allows some molecules through but not others.
- Concentration Gradient: "The relation of two given areas, where the concentration of a particular substance differs between those areas." (Biology-Online.org)
- ATP: Adenosine Triphosphate. An organic chemical which stores and releases energy for use within body cells, and which is critical to cell activity.
