Osmosis Triple Science EssayIntroductionIn this investigation I am probe if varying the amount of sugar solution or distilled water determines the density of prison booth sap. I ordain do this by using different concentrations of sugar solution and distilled water. If the medium is hypotonic a alloy solution, with a higher water concentration than the cell the cell will gain water by osmosis. However if the medium is isotonic a solution with exactly the same water concentration as the cell there will be no net movement of water across the cell membrane. If the medium is hypertonic a concentrated solution, with a lower water concentration than the cell the cell will lose water by osmosis.Investigation variablesTo have a controlled reliable investigation I will control the following variablesTo try my best to do the experiments at the same room temperature.I will prepare the cultivated carrots in the same way beca engross any minor changes can ruin the experiment.The grass of the carrots is a dependent variable and this terminology means that the piece of carrot will be metric constantly throughout the experiment. I will measure in grams, in addition the piece of carrot will be measured before and after it is put into the solution, this will allow us to date stamp if any osmosis has taken place.Fourthly the volume of the solution which the carrot pieces are put in mustiness be same for all of them for example all of them should be covered in what is supposed to be covered in. Also I am going to use the same set of scales to measure the carrot pieces in the solution. This is because measurements may vary between the scales.I did this in a lab so everything was beneath control to make my results very reliable.My hypothesisI predict that the less sugar solution we use the higher the concentration of the cell sap would be.PlanFirst I will take some(prenominal) xylem cells from inside of the carrot and some phloem from the outside of the carrot I will take 15 samples of each type of cell from each carrotI will put 3 samples in each solutionI would then leave it for 1 hourThen I would reweigh its fixThen plot these results onto a graphAnd then where the line crosses 0 is the concentration of the cytoplasm remnantAs I conclude I can say that in my investigation I effectuate out that the more sugar solution you cover in the carrot piece the higher the concentration of cell sap would be and there would be more osmosis activity. However what does mystify me is what you can match above, the two outliers because they don not surprisingly fit with the others but I am sure that if we do this investigation again there would be two outliers or less.
