Investigate the Osmosis in Potato Rods in Various Concentrations of Sal

Investigate the Osmosis in Potato Rods in Various Concentrations of common salt SolutionsIntroductionOsmosis is the movement of pee molecules across a partially leaky membrane from a region of full(prenominal) wet capableness to a regionof low water effectiveness. It can be makeed by several disparatevariables including denseness of salt solutions. When a plant cubicleis put in pure water it leave become big and it will non burst dueto the presence of a kiosk wall and a large permanent vacuole and whenit is put in a punishing solution it will be plasmolysed, on theother wad when an animal cell is put in pure water it will burst dueto the absence of the cell wall which is only record in the plantcell and if is plant cell is put in a concentrated solution it willshrink.What is the water potential?The water potential of a solution is a measure of whether it is likelyto recur or gain water molecules from another solution. A profanesolution, with its high immersion of water molecules is said tohave a higher water potential than a concentrated solution, becausewater will flow from the dilute solution to the concentrated solution (from a high water potential to a low water potential).Pure water has the highest water potential because water moleculeswill flow from it to any other aqueous concentrated solution even ifthis solution is a highly dilute solution.Variables that affect the osmosis process in the potato rods Independent variables The Difference in preoccupation of saltsolutions This will affect the osmosis in the plant cell as I willprep be five different submersions of the salt solutions and theyare 0.0, 0.3, 0.5, 0.7, 1.0and this is how they are prepared- For preparing the concentration of 0.0 I used pure water.- For preparing the concentration of 0.3 I thrifty 3 cm3 of the salt solution by victimization the syringe and poured it into the test piping that is labeled 0.3, indeed I metrical 7 cm3 of water and poured it into the sa me test tube.- For preparing the concentration of 0.5 I measured 5 cm3 of the salt solution and poured it into the test tube that is labeled 0.5, then I measured 5 cm3 of water and poured it into the same test tube.- For preparing the concentration of 0.7 I measured 7 cm3 of the salt solution and poured it into the test tube that is labeled 0.7, then I measured 3 cm3 of water and... ... points on thegraphs were plotted as absolutely as possible practically.All my results support my prediction I made and assistanted me to make astrong drive in the graph.Although, I might have got few anomalous results save that is to beexpected, I may be have measured any substance which I am using wrongor not accurately. I repeated the audition two times to get theaccurate average results and to ensure that I had not made anymistakes and so as not to have any anomalous results in my experimentand there wouldnt be any chance for error to occurs.My results seem true(p) as I am basing my res ults reliability on a meditation and my own prediction. I repeated the same experimentsusing different concentration of the salt solution or change thetemperature so as to help the rate of osmosis in the potato rod.Also for more accurate results, I could extend my coursework bytesting the same brand of potatoes using different substances. By thisI mean using a different subject instead of salt, i.e. sugar or maybeany fruit juice. consequently I could find out whether osmosis occursdifferently with different things diluted in the water. I could evenuse different vegetables and fruits.
