Osmosis is the diffusion of free water molecules from an area of high concentration to an area of low concentration of free water molecules. It is important that you know what these terms mean. View Lab Bench Osmosis diffusion lab AP Biology 1doc from BIOLOGY MISC at James Madison High School.
In the following laboratory you will observe the process of diffusion and osmosis across cell membranes. Course Title SCIENCE NA. When the concentration levels of two solutions on either sides of the membrane are equal and no movement is detected the solutions are isotonic.
Review your class notes and check your textbook for definitions of the following terms. Pages 1 This preview shows page 1 out of 1 page. Hypothetically use red blood cells to explain osmosis and states of tonicity.
Go to the Lab Bench. The movement of molecules from areas of higher concentration to areas of lower concentration is called diffusion. Paul Andersen starts with a brief description of diffusion and osmosis.
