Introduction:

Osmosis is the diffusion of water across the plasma membrane of a cell. Basically, this is when the molecules move from an area of higher concentration to an area of lower concentration. A solute is the smaller part of a solution that is dissolved by a solvent. A solvent dissolves the solute, which then forms a solution, which is a mixture of two or more substances. There are three main kinds of solutions when it comes to solutes and solvents. These three solutions are called isotonic solutions, hypertonic solutions, and hypotonic solutions. An isotonic solution is a solution

A hypertonic solution is a solution in which there is a higher amount of solute concentration than in the cell. This also means that there is less water concentration than in the cell. Finally, we have a hypotonic solution. A hypotonic solution is the opposite of a hypertonic solution, in that it has a lower solute concentration than the cell. Since it has a lower solute concentration, it has a higher amount of water than the cell. All three of these solutions produce very different results when a cell is placed into them. If a cell (or in this case, deshelled eggs) is placed into an isotonic solution, there will be no change in the weight of the cell because no water will have entered or left the cell. However, if a cell is placed into a hypertonic solution, the cell will lose weight because water will leave the cell and go into the solution. As a result, the cell will shrivel up. This happens because in a hypertonic solution, there is more solute than water. And in an isotonic solution, the cell will gain weight because water will rush into the cell from the solution. Again, this happens because there is more water in the solution than solute, so the

These glass dishes hold the deshelled eggs. The egg was dried each time before weighing it so the weight would be of the egg only, and not the water. This was done four times throughout the experiment; once before it was initially weighed, again after being in the solution for fifteen minutes, again after being in the solution for thirty minutes, and again after being in the solution for forty-five minutes. After the egg was dried each time, it was put on the scale to be weighed. The egg was weighed after it was taken out of the solution. This happened at the same time intervals as the drying process (beginning, fifteen minutes, thirty minutes, forty-five minutes). After each time the egg was weighed, the weight of the egg (in grams) would be recorded on a table, so it could be tracked throughout the
