Summary:
Details an experiment making key observations about the processes of diffusion and osmosis. Answers why and how particular molecules are able to diffuse through the cell membrae.
Osmosis and Diffusion Lab
I.Purpose: The experiment will allow us to make key observations about the processes of diffusion and osmosis. This activity will allow us to give us an answer to why and how particular molecules are able to diffuse through the cell membrae. With this experiment, we will understand the essential factors that allow molecules to diffuse in and out of the cell membrane. We will be able to investigate how the role the structure of the cell membrane plays in permeability. After finishing this experiment, we will increase our knowledge of diffusion and osmosis in a molecular explanation.
