What do these pictures have in common? The egg and potato act as great models of the structure and function of the cellular membrane. This week we will be talking about cell membranes, and we will be using the eggs to show how the process of osmosis and diffusion occur. We will also be working with potatoes to observe the effects that passive transport has on cells. The cell membrane is an important structure for the cell because it protects the cell from outside materials. However, the membrane is able to do so much more, including:
- *passive transport (osmosis)
- channels materials through proteins
- communicate with other cells
*Topics this week: active transport, passive transport, endocytosis, exocytosis, osmosis, diffusion, structure of the cell membrane.
