Water diffused into the cells of the potato because there was a higher concentration of water outside than inside the slice. 4. — The salt solution causes water to move out of the swollen cells (tissue), reducing the swelling and relieving the pain. — The loss of water by the cells. Part 2—Diffusion Of Water Across a Membrane (Osmosis) Osmosis is a special type of diffusion. Specifically, it is the diffusion Of water across a membrane. Osmosis is a very important process because it enables cells to maintain the proper water balance. NYS Regents Lab Activity #5. Diffusion Through a Membrane. Important Terms Diffusion.

Selective Permeability of Dialysis Tubing Lab: Explained. These concepts can be very difficult for students to understand. In order to give them a view of how diffusion works with a semipermeable membrane, I like to do a lab that uses a plastic bag to model the cell (membrane). It is a simple lab where students do very little except watch the process and record data and information.
