Osmosis AT1

Conclusion: What I take up inst totally turn up is that the higher the preoccupancy of sucrose the higher up was the stump spud silicon chip in the test tube. The pissing inwardly the spud is moving from a area of high body of piddle system tautness to an area of minuscule denseness so in the sugar concentrated solutions the potato chip should lessening in mass my tops understanded the opposite of two my soothsaying and the generator where I adapted information from. {CGP Books} give tongue to my soothsaying was correct thus proving something has gone wrong during the try by chance I did not leave it abundant abounding for the osmosis to occur. In other words the water inside the potato is going outdoor(a) 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 detain agniseed lading therefore bec ame turgid. In the potato chip there is the point at which the potato cell set up reach its highest point of turgidity. The trends or patterns that I have rustle out are that with each of the look into the line of the vivid record is up and down then straight. I animadvert that the results of the experimentation 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 have it away 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% s ucrose solution. There was zero weight loss ! for the distilled water and the 0.4% sucrose solution, this implicates 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 move around in and out of the potato by diffusion. The following is a diagram to show how this happens: This process normally happens in disposition 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 prospicient and I changed it to 4cm because it was difficult to fit the chip into the test tube. This renewal was done to all the potato chips. This change was relatively lightheaded to micturate, and this could be easily performed. I think I took unsparing results for the metre of solutions that I was tendin g(p), and the time restrictions that I had to follow, (30 mins). However presumption a greater time period, I could have investigated more(prenominal)(prenominal) concentration in terms of molarity. Also I could have recurrent 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 testament allow me to obtain average results, which will be more representative than having results from another person in the class. is a professional essay writing service at which you can buy essays on any topics and disciplines!

instead to make my experiment better I could have asked more students within my class for th eir result to come up with a more surgical average r! esult. I could have similarly use a machine to cut the potato chips so that all 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 monetary standard to 1/100 of a gram this could show evening 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 lawsuit when the distilled water and 0.4% sucrose solution didnt change in mass. perchance this may have been caused by world error, or by chance 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 need about human error by getting mach ines 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 partake in change in mass with solutions using a turnaround substance. By this I mean using a severalise vegetable, perhaps celery or cucumber. Then I could muster 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:
