Register to read the introduction… It is diffusion within a cell that is essential for it to survive. Water diffuses either in or out of the cell membrane when certain situations arise. The water, however does not diffuse to suit the plants best interests, it will just go from a concentrated area to a less concentrated area (i.e. less water). Despite this, often, having a bad effect on the plant. Osmosis is designed to balance the amount of water either in, or surrounding, a cell so that it does not contain too much water, in which case, it will diffuse outside of the cell membrane or too little water, in which case, water will diffuse inside the cell. The natural state of a plant most of the time is turgid because enough water has been absorbed to keep the plant healthy so it can support itself. However if it is flaccid then the surroundings are too concentrated and therefore water is being transported from inside the cell to …show more content…
However, to be more exact, it shows the change in length of three different sets of six potato samples (Results 1, Results 2 and the Trial Experiment Results), after they have been placed in one of the six sugar solutions of various concentrations. The X-Axis of the graph is labeled ‘Solution', and indicates which one of the six solutions the potato sample was placed in, and the Y-Axis of the graph is labeled ‘Length Change (mm)', and indicates the overall change in length of the potato sample after being placed in one of the solutions. These two axes allow each individual result (indicating the length change of a particular potato sample) to be plotted onto the graph, producing a graph with 3 sets of 6 individual results (with the individual results, from each set marked in a particular colour). This gives a reasonably clear representation of the results (one, which, is at least better than that given by the results tables), however, these trends still do not show, as clearly as possible, the overall trend of each set of results. So, finally, three lines of best fit must be drawn on the graph, to clearly show the overall pattern (or the correlation) followed by the …show more content…
Therefore causing it to diffuse into the surrounding solution, to correct the imbalance (this would have to occur as, according to the rules of diffusion (or osmosis) the water must travel from an area high concentration of water, in this case the potato sample, to a lower concentration of it i.e. the surrounding solution (this water movement could be proven, by testing the new concentration of the solution, after osmosis is allowed to take place). Eventually, as was seen in some of the results, the mass change would become a negative value i.e. the mass of the potato would
