The water moves to the higher concentration to dilute it/maintain homeostasis, increasing or decreasing mass depending on whether it goes in or out. 2. According to the graphed data (attached) gathered from this lab, the approximate concentration at which the solution and potato cytoplasm is isotonic is 0. 4 mol/L. Can therefore conclude that the approximate solute concentration of potato cytoplasm is also 0. 4 mol/L. This is because the concentration of potato cytoplasm never changed throughout the experiment, UT the sucrose solution did.
Seeing as isotonic means both concentrations are equal, I can conclude that the potato cytoplasm was always around 0. 4 moll L. 3. I suspect that the mass of the potato would decrease just as it did with the sucrose solution because the solution would still be hypersonic to the potato. 4. The potato cytoplasm is permeable to water, but sugar is not. 5. Distilled water would keep the vegetables crisper. This is because the water/solution would be hypotonic to the vegetable, making the water flow into the vegetable keeping t crisp. 6.
It’s important that they are the same concentration so that they are isotonic. If the chemicals were either hypotonic or hypersonic to the blood plasma, it could result in lists or creation of blood cells. 7. The responding variable would be the change in mass of the potato cytoplasm, and the manipulative variable would be the solute concentration of the sucrose solution. Conclusion: In order to find the solute concentration of the potato cytoplasm we calculated the difference in mass while controlling the concentration of the sucrose solution.
We then graphed our findings, and used a best-fit line to find the approximate concentration of potato cytoplasm. In conclusion, we found that as the concentration of sucrose decreased, the change in mass increased; the concentration of potato cytoplasm to be 4. Mol/L, and the membrane to be permeable to water but not sugar. This can be related to every day life in understanding how a semi-permeable membrane and diffusion relate. A cell, when suspended in a hypotonic or hypersonic solution will release or absorb water to reach isotonic. A good example would be with our red blood cells.
