Osmosis Lab: Potatoes and Elodea Background Information: Cells have a need to regulate their internal environment. They need to be able to this because cells often find themselves in environments where the concentration of dissolved solids outside the cell is different from the number of dissolved solids inside the cell. Since the solids can not move across the membrane‚ the cell responds by moving water either into or out of the cell in an attempt to balance the number dissolved particles.

Osmosis of a Potato cell. Hypothesis is that the potato in saltwater is going to show that it will break down the cells of the potato. Osmosis is the diffusion of a solvent through a semi-permeable membrane‚ from a solution of low solute concentration to a solution with high solute concentration‚ up a solute concentration gradient. Net movement of solvent is from the less-concentrated to the more-concentreated.‚ which tends to redure the difference in concentrations. This effect can be countered

of some mistake". In the play Fences by August Wilson‚ the main character Troy Maxson proves himself to be a hero in my eyes‚ the way he cares for his family illustrates his heroic efforts.
