Conclusion: What I take up inst only step up is that the higher the preoccupancy of saccharose the higher up was the white potato silicon chip in the test tube. The pissing inside the spud is moving from a area of high piss system tautness to an area of minuscule density so in the sugar concentrated solutions the potato chip should go down in mass my settlements understanded the opposite of two my forecasting and the writer where I adapted information from. {CGP Books} give tongue to my farsightedness was correct thus proving something has gone wrong during the try possibly I did not leave it abundant abounding for the osmosis to occur. In other words the body of water inside the potato is go forward it, as it is passing from a weak concentration to a strong concentration. Making it smaller and lighter. Where as with water as the solution, the potato piece stayed the comparable but theoretically it should cut back pull ined exercising weight in that respectfore became turgid. In the potato chip there is the point at which the potato cellphone set up reach its highest point of turgidity. The trends or patterns that I have rig out are that with each of the look into the line of the graphical record is up and down then straight. I study that the results of the audition disagree with my prediction. I think that they disagree with my prediction as when the concentration of the saccharose solution gets higher the to a greater extent tour the potato piece becomes, we notice this is correct however my results didnt count to essay it. When it was 0.8% it should have the highest weight passing play but my results show that it increased by 1gram. Also when the potato was put into the distilled water, we had found that it had interpreted on the least weight: completely defying with my prediction. The highest fair mass gain was for the 0.6% sucrose solution. The highest average mass divergence was for the distilled water and 0.4% sucrose solution. There was zero weigh! t loss for the distilled water and the 0.4% sucrose solution, this think abouts that no water melt down into the cell to increase its mass or no water go out of the cell to decrease its mass. Osmosis ca gives water to propel in and out of the potato by diffusion. The following is a diagram to show how this happens: This process normally happens in tendency when the root hairs of a root take in water by osmosis it happens when water goes into the soils the root hairs cover a macroscopic surface area and when the water goes on to the root hairs it diffuses into them and is taken up to the leaves via the xylem. Evaluation: Originally the potato chip was 5cm extensive and I changed it to 4cm because it was difficult to fit the chip into the test tube. This transition was done to all the potato chips. This change was relatively clean to manufacture, and this could be easily performed. I think I took overgenerous results for the center of solutions that I was tending(p) , and the time restrictions that I had to follow, (30 mins). However given up a greater time period, I could have investigated much(prenominal)(prenominal) concentration in terms of molarity. Also I could have tell the experiment at least four times. This could have all been done at once; by this I mean that the four identical experiments running at the analogous time. This ordain allow me to obtain average results, which will be more representative than having results from another person in the class.
instead to make my experiment better I could have asked more students inwardly my class for their result to come up with a more surgical average result. I coul! d have similarly utilize a machine to cut the potato chips so that either chip would be identical and this eliminating compassionate error. If I were doing the experiment again I could make changes, some as mentioned above, I would use a top pan offset that would pulse to 1/100 of a gram this could show pull down slight variations in mass. I would also use a digital measurer to get a more accurate result to ensure that I have a same amount of fluid in each test tube. or else I could use a burette. There were some irrational results for modelling when the distilled water and 0.4% sucrose solution didnt change in mass. mayhap this may have been caused by military man error, or maybe the potato chip was not cut accurately. My results did go away a lot with others for the same concentrations. My results were consistent, and there were no results that were poor. If I were to extend/improve my method I would eliminate the mold about human error by getting machines to do the cutting and the other aspects of the experiment that could have been caused by human error. I could extend my enquiry by testing the helping change in mass with solutions using a contrary substance. By this I mean using a distinguish vegetable, perhaps celery or cucumber. Then I could burn down out whether osmosis occurs with the same patterns and trends with any vegetable. If you want to get a full essay, order it on our website: OrderCustomPaper.com
