Osmosis :: essays research papers

These results sight that a white tater chip placed in body of urine lead gain in length, a weak abrasion solution volition lose length and a strong swag solution provide lose length also. The results from this test provide solelyow me to choose an earmark range of moralities in order to find out(a) what the compactness is deep down the cadre vacuole. I am going to check out 0.0, 0.2, 0.4, 0.6, 0.8 and 1.0 molar profit solutions. I drive chosen these concentrations to try and accurately find when thither is no net movement of water, hence the concentration of the cellular phone vacuole. From old work done on osmosis, I hazard that molarity and average out change in people/ length volition be indirectly proportional. I retrieve on that prove depart be a contradict correlation between the two. I think that there forget be both loss and gain in mass disc all overed. I think the graph will look like this 89/5489/15489/image005.jpg" align=" left ove r(p)" hspace="12">but there will be no plasmolysed on my graph, as I do no sway my measurements to go that far. I hope to be able to identify the point when there is no net movement of water. Analysis of Results The Consequences of Osmosisin plant cells set up cells always have a strong cell w each(prenominal) border them. When the take up water by osmosis they start to swell, but the cell wall prevents them from bursting. comprise cells become "turgid" when they ar put in dilute solutions. magnanimous means swollen and hard. The pressure inside the cell rises, eventually the familiar pressure of the cell is so high that no more water can enter the cell ......The type of potatoes themselves will have to be kept the same all the way with the experiment. This is because each potato may have a divergent tissue layer and a different amount of pores. Also the water content in each potato could vary. This can be explained by saying that the potatoes in the m iddle of the evict will have a higher water content, because it is more wet in the middle of the sack which is opposite to the potatoes on the outside of the sack. To necessitate rid off this unfairness, I will pre-treat all the potatoes that I will use in my experiment. This means that I will keep all my potato cylinders in the same environment over night in a beaker full of sucrose solution. When plant cells (potatoes) are placed in concentrated sugar solutions they lose water by osmosis and they become "flacc .Osmosis essays research papers These results show that a potato chip placed in water will gain in length, a weak sugar solution will lose length and a strong sugar solution will lose length also. The results from this test will set aside me to choose an appropriate range of moralities in order to find out what the concentration is inside the cell vacuole. I am going to investigate 0.0, 0.2, 0.4, 0.6, 0.8 and 1.0 molar sugar solutions. I have chosen these concent rations to try and accurately find when there is no net movement of water, hence the concentration of the cell vacuole. From previous work done on osmosis, I predict that molarity and average change in mass/ length will be indirectly proportional. I think there will be a negative correlation between the two. I think that there will be both loss and gain in mass discovered.

I hope to be able to identify the point when there is no net movement of water. Analysis of Results The Consequences of Osmosisin plant cells Plant cells always have a strong cell wall surrounding them. When the take up water by osmosis they start to swell, but the cell wall prevents them from bursting. Plant cells become "turgid" when they are put in dilute solutions. Turgid means swollen and hard. T he pressure inside the cell rises, eventually the internal pressure of the cell is so high that no more water can enter the cell ......The type of potatoes themselves will have to be kept the same all the way through the experiment. This is because each potato may have a different membrane and a different amount of pores. Also the water content in each potato could vary. This can be explained by saying that the potatoes in the middle of the sack will have a higher water content, because it is more humid in the middle of the sack which is opposite to the potatoes on the outside of the sack. To get rid off this unfairness, I will pre-treat all the potatoes that I will use in my experiment. This means that I will keep all my potato cylinders in the same environment over night in a beaker full of sucrose solution.
