|The Cell: Passive Transport Osmosis||A Learning Object on Osmosis and how it affects the living cell, hosted at the Wisconsin Online Resource Center.|
|The Cell: Passive Transport Diffusion||Also at the Wisconsin Center, this learning object describes the process of diffusion in liquids and outlines the concept of a concentration gradient.|
|Concentration Gradients (RLO)||An RLO which describes the concept of concentration gradients in biological systems through analogy with gradients found in everyday life, and outlines passive and active transport across cell membranes.|
|Diffusion and Osmosis||A brief but clear tutorial on diffusion and osmosis, including osmotic pressure and membrane transport, from a Physics perspective.|
By completing this resource you will be able to:
- explain the difference between the processes of diffusion and osmosis
- have a greater understanding of the concepts of concentration gradients and tonicity
