10/14/2011~Diffusion through a Membrane lab


http://www.youtube.com/watch?v=2Th0PuORsWY



The Diffusion through a membrane laboratory activity illustrates how large molecules (Starch) can not fit through a simulated cell membrane where as small molecules (Glucose) can pass freely. We will be discussing indicator solutions (Iodine, and Benedicts) to visibly see the presence or absence of compounds in a solution.


Homework:  Make any test corrections directly on your cell unit test if you would like to improve your grade.
