“Different Solutions Affect Cells” The purpose of this laboratory was to observe how a cell, in this case a chicken egg, reacted in different solutions. The solutions used in this experiment were: vinegar, syrup, and water. Depending on the solution, a cell will change in size. After being left in vinegar, the eggs calcium shell dissolved. This allowed the semi-permeable membrane to be exposed. The egg became bigger in size. The raw egg, before being in vinegar measured 120 millimeters (mm) in width and 140mm in length. After being in vinegar, the egg measured 150mm in width and 200mm in length. Therefore the eggs width grew by 30mm and 60mm in length. This evidence supports the hypothesis that: the egg will get bigger when placed in vinegar. The egg grew because the water from the vinegar diffused into the egg. The water concentration in the egg was higher than the water concentration inside the egg yolk and egg white. Water molecules move from where there’s a lot to where there’s a little water concentration which is called osmosis. This makes vinegar a hypotonic solution. After being left in syrup, the eggs calcium shell hardened. The egg became smaller in size. The raw egg, before being dropped in syrup it was put in vinegar and it measured 150mm in width and 200mm in length. After being in syrup, the egg measured 170mm in width and 160mm in length. Therefore the eggs width shrank by 30mm and 10mm in length. This evidence supports the hypothesis that: the egg will get smaller when placed in syrup. The egg shrank because the water from the egg diffused into the syrup. The water concentration in the egg was higher than the water concentration inside the syrup. Water molecules move from where there’s a lot to where there’s a little water concentration which is called osmosis. This makes vinegar a hypertonic solution. After being left in
