Investigate the Osmosis in Potato Rods in Various Concentrations of Sal

Investigate the Osmosis in Potato Rods in Various Concentrations of Salt Solutions psychiatric hospitalOsmosis is the movement of piddle molecules across a partiallypermeable membrane from a office of high water electric say-so to a regionof low water potential. It can be affected by several(prenominal) differentvariables including tightness of season re firmnesss. When a plant cellis sic in pure water it willing become turgid and it will not wear out dueto the presence of a cell mole and a large permanent vacuole and whenit is put in a satu pass judgmentd solution it will be plasmolysed, on theother hand when an brute cell is put in pure water it will burst dueto the absence of the cell wall which is only present 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 lose or gain water molecules from another solution. A dilutesolution, with its high concentration 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 lick in the potato rods Independent variables The Difference in concentration of saltsolutions This will affect the osmosis in the plant cell as I willprep atomic number 18 five different concentrations 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 measured 3 cm3 of the salt solution by using the syringe and poured it into the test tube that is labeled 0.3, then I measured 7 cm3 of water an d poured it into the same 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 plan as accurately as possible practically.All my results supported my divination I made and helped me to make astrong trend in the graph.Although, I might have got few anomalous results but that is to beexpected, I may be have measured any internality which I am using wrongor not accurately. I repeated the experiment two times to get theaccurate fairish results and to ensure that I had not made anymistakes and so as not to have any anomalous results in my experimentand in that respect wouldnt be any chance for error to occurs.My results seem reliable as I am basing my results reliability on ahypothesis and my take 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 melt down my coursework bytesting the same brand of potatoes using different substances. By thisI mean using a different thing kind of of salt, i.e. sugar or maybeany fruit juice. Then I could find out whether osmosis occursdifferently with different things diluted in the water. I could evenuse different vegetables and fruits.
