Membranes, Osmosis & Diffusion

Today we discussed the details of the cell membrane.  What is it made out of?  As well as how do things move from one side to the other.


Concentration gradients help drive the movement of substances in and out of a cell, which in turn relates to osmosis and diffusion.  Here's the animation on osmosis and diffusion that we watched in class.

Homework: Study for your test tomorrow.
