Elodea And Salt Water Experiment

To conclude, the hypothesis was supported by the data obtained. The hypothesis stated, if an elodea leaf is exposed to salt water then, the leaf cells will experience plasmolysis because the cells will be in a hypertonic solution. As seen in the above data table and bar graph there was an obvious difference between the length of a cell in tap water and the length of a cell in a 10% salt solution. As seen in the row of the data table labeled difference in length between length before being introduced to the salt solution and after being introduced to the salt solution. The differences between the length of cells in tap water and salt solution are shown. In trial one there is a zero micrometer difference in cell length, in trial 2 there is a 10.116

The average length of a cell in tap water is 90.0588 micrometers and the average length of a cell in a 10% salt water solution is 75.1838. In comparison the differences between the averages are striking. Demonstrating that the length of the cell shrinks and is undergoing plasmolysis when the salt water solution was introduced to the previously standing cells in tap water. Plasmolysis is the shrinking of the cytoplasm away from the cell wall. Plasmolysis is occurring because when the 10% salt solution is introduced to the elodea leaf the cells in the elodea leaf are submerged in a hypertonic solution. Meaning that there are more solutes outside the cell rather than inside the cell. The solution is hypertonic because the NaCl which composes salt has a high electronic pull. Causing the H2O in the water to attract to the NaCl. When submerged in the salt water solution the elodea leaf cells water is being attracted to the NaCl electric pull so by diffusion the water is pulled out of the
