onion cell plasmolysis lab hypothesis - UNP
However, when the distilled water is replced by the 25% solution a majority of the cells become plasmolyzed.Onion Cell Story:When salt is introduced to the surrounding environment, the NaCl molecules are too big to pass through the cell wall.

distilled water saturated had mostly turgid cells
3% NaCl(q) saturated had some turgid cells and some plasmolyzed cells
25% NaCl(q) saturated had mostly plasmolyzed cellsThe vacuoles of the cell filled with water when saturated with distilled water.

25% salt water was next added to the membrane and plasmolysis of the onion cells were observed.Relating observations 1 and 2 we can say that the molecules moved from inside the onion cell to the outside area because the outside area had a higher concentration.

8 micrometer microspheres moved 3.95 micrometers in 5 minutes
4 micrometer microspheres moved 10.4 micrometers in 5 minutes
2 micrometer microspheres moved 143 micrometers in 5 minutesOur findings support the thesis that says that water molecules are continuously moving, and the smaller the object was the more it moved.Experiment 2:3% salt solution made almost all of the cells turgid but a few of them were partially plasmolyzed.
0% salt solution made the cells even more turgid, and filled out the ones that were plasmolyzed earlier.
25% salt solution made the cells very plasmolyzed.When there is salt in the environment outside of the cell, it takes water away from the inside of the cell, making the cell plasmolyzed.
