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. |
| Pathways
Into and Out of the Cell |
An excellent tutorial from the BBC
Biology series, aimed at AS-level
students. A short tutorial examining the processes of active and passive
transport in living cells, and moving on to endocytosis and exocytosis
(processes enabling cells to transport large amounts of material
across plasma membranes). |
| Cells
& Transport (movies) |
A nice collection of Quicktime movies illustrating various aspects
of cell transport. Of most relevance to this RLO are the animations
of active transport and diffusion. |
