Osmosis. 2 Diffusion of water across a membrane Diffusion of water across a membrane Moves from high water potential (low solute) to low water potential.

Diffusion The movement of molecules from an area of high concentration to an area of low. concentration.

O SMOSIS L AB Osmosis: the movement of water molecules from a region of lower solute concentration to a region of higher solute concentration.

Bio Chem and Cell Membrane Water Potential Try These AP Biology 12 Bio Chem and Cell Membrane Water Potential Try These

Try This! The data displayed on the graph were collected in an experiment studying the effect of changes in solute concentration on the mass of tissue cells. What solute concentration is isotonic to the cells? Explain why

Try This! The data displayed on the graph were collected in an experiment studying the effect of changes in solute concentration on the mass of tissue cells. What solute concentration is isotonic to the cells? Explain why

Try This! If you place a red blood cell in a hypotonic solution, what happen and why? How is this different than if you placed an onion cell in the same hypotonic solution?

Water Potential

Try This! A dialysis tubing was filled with 0.20 M MgCl2 solution and placed inside a beaker of distilled water at 20°C. What is the initial solute potential inside the dialysis tubing? What is the initial water potential inside the dialysis tubing and the initial water potential outside in the beaker? Use the concept of water potential to explain why osmosis will occur.
