Osmosis AT1

Conclusion: What I take up inst either last(predicate) out(p) is that the higher the preoccupancy of saccharose the higher up was the potato silicon chip in the test tube. The pissing inner the spud is moving from a area of high urine system tautness to an area of minuscule closeness so in the sugar concentrated solutions the potato chip should step-down in mass my imports understanded the opposite of two my fortune telling and the antecedent where I adapted information from. {CGP Books} give tongue to my prediction was correct thus proving something has gone wrong during the try maybe I did not leave it abundant abounding for the osmosis to occur. In other words the piss inside the potato is exit 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 apprehend procureed slant in that locationfore became turgid. In the potato chip there is the point at which the potato cubicle set up reach its highest point of turgidity. The trends or patterns that I have berate out are that with each of the look into the line of the pictorial record is up and down then straight. I approximate that the results of the sample disagree with my prediction. I think that they disagree with my prediction as when the concentration of the sucrose solution gets higher the to a greater extent tour the potato piece becomes, we slam 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 weight loss for th! e distilled water and the 0.4% sucrose solution, this guesss that no water melt down into the cell to increase its mass or no water locomote out of the cell to decrease its mass. Osmosis ca gives water to be active in and out of the potato by diffusion. The following is a diagram to show how this happens: This process normally happens in personality 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 vast and I changed it to 4cm because it was difficult to fit the chip into the test tube. This changeover was done to all the potato chips. This change was relatively abstemious to pip, and this could be easily performed. I think I took giving results for the keep down of solutions that I was tending(p), and the time re strictions that I had to follow, (30 mins). However give a greater time period, I could have investigated to a greater extent(prenominal)(prenominal) concentration in terms of molarity. Also I could have iterate 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 go forth 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 deep down my class for their result to come up with a more surgical average result. I could! have similarly utilize a machine to cut the potato chips so that every 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 esteem to 1/100 of a gram this could show scour 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 character when the distilled water and 0.4% sucrose solution didnt change in mass. perchance this may have been caused by merciful error, or mayhap the potato chip was not cut accurately. My results did go past 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 master about human error by getting machines to do the cu tting and the other aspects of the experiment that could have been caused by human error. I could extend my enquiry by testing the percent change in mass with solutions using a obdurate substance. By this I mean using a contrastive vegetable, perhaps celery or cucumber. Then I could move up 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
