Osmosis Experiment
Osmosis Lab Report
The essential focus of the experiment was to acquire data for the mass change resulting from osmosis in order to determine the carbohydrate solution of the carrot cells. The carrots were a vegetable used within the experiment with a carbohydrate solution around .5 M. The hypothesis is if there are carrots in different carbohydrate solutions then there will be a percent change in mass. The carrots have large vacuoles that hold water, this allows the mass to increase when the hypertonic solution is .2 M and 0 M, around .4 M the mass stays near the same because it is an isotonic solution, lastly the mass decreased when the hypotonic solution is .6 M and above. The experiment was developed with 6 plastic cups containing varying …show more content…
The data does support the hypothesis because each solution had caused a change in mass in each individual carrot. The graph depicts the [sucrose] of the carrot cells to be around .5 M. From .0 M to .2 M, the movement was water went into the carrot cells, this is due to the fact that the change of mass had increased. While .04 M from our data signifies that closest solution tested to an isotonic solution. This means that the water did not move in or out of the cell because both of the solutes were equal. From .06 M to 1 M, the water went out of the carrot cells, this is based on the change of mass of the carrots decreasing in these solutions. The room temperature and surface area versus volume both play a part in being a possible extraneous variable. Room temperature would fluctuate the fluidity of the solution, which would influence the end results. The surface area versus the volume influences the efficiency of the cells. For instance, if the SA:V has a large ratio between the two, this signifies that the cell is small and therefore will efficient. However, if the SA:V ratio has a smaller ratio, the cell is too big, and thus decreasing its
