      Osmosis is a passive process in which water is driven into or out of a cell by pressure due to the concentration gradient (amount of solutes dissolved in the water). The water will move in or out in order to have an equal concentration of solute on each side of the cell membrane. The solution concentration affects tonicity (shape or tone).

      In Part II of the lab you will address the following questions on osmosis and tonicity: What is tonicity – hypotonic, isotonic, hypertonic and how does it affect osmosis? Tonicity refers to the concentration of salts outside of the cell compared to inside the cell. It will influence the passive diffusion of water in and out of the cell.

      Part 1: Osmosis across an egg cell membrane. To examine the effects of tonicity on osmosis across cell membranes you will examine the movement of fluid across the membrane of an egg that has been de-calcified by decalcification (24 hr soak in vinegar) to remove the calcium egg shell and expose the egg cell membrane.

      In the tonicity activity today we’ll see that the concentration of solutes inside and outside the cell is critical to cell shape, function and survival. Concentration always relates the amount of solute to solvent in a solution, but the amounts can be expressed as mass, volumes, or even in terms of the number of atoms, molecules or particles.
