Osmosis Lab Report

In order to understand the plasmolysis and hemolysis experiments we must first know what osmosis is. Osmosis is the movement of water from particles through the plasma membrane from an area of higher concentration to an area of low concentration. Both animal and plant cells undergo osmosis. The results of the cells vary due to the movement of water from high to low concentrations. Hypotonic, isotonic and hypertonic solutions all results with in the cell. In the animal blood cell experiment, the cell under goes a hypotonic solution in which water moving from the outside of the cell to the inside of the cell causes the cell to swell up and burst this processes is called hemolysis. In the plant cell experiment, the cell under goes, a hypertonic solution in which water moved from inside the cell to the outside of the cell causes it to

In the first tube, 1.8 percent of NaCl concentration was added and was excluded from the addition for Volume Distilled H2O. The second test tube, 0.9 percent of NaCl concentration was as well as 0.5ml of distilled water. In the last test tube, no NaCl was added while 1.00ml of water was. Each test tube was mixed for one to five minutes after adding the solutions. Then observed if the tubes appeared clear or vicious. In the elodea experiment, three tiny leaves were removed from the Elodea plant and places onto test slides. Distilled water was added to test slide A. In test slide B, 0.9 percent of saline solution was added and 5 percent in test tube C. A cover glass was added to all and then each observed under the microscope. In order to test our predictions Test slide C with the 5 percent saline was observe one more time, but this time adding distilled water. The distilled water was added using a droplet on one side and in the other, a napkin absorbed the saline
