Diffusion and Osmosis

This video does a good job overviewing the cell membrane and transport:

This is a Bozeman Science Video from the Biology Essentials Series on Cell Transport.

This is another good look at diffusion and osmosis

Just thought a couple videos like this might help review what we covered in class about the cell membrane.

In case you wanted to look at the image from class to help your drawing (or labeling) I have included it here: Fluid Mosaic Model

Below are some videos to help clarify the concept of Homeostasis.

This final video actually begins to link us to the next class covering the plasma membrane (remember our analogy of it acting like a bouncer at a club?).
