Osmosis in Potato Strips - Bio Lab
Therefore, the three states of an environment hypertonic, hypotonic and isotonic determine the movement of water across the membrane . For instance, if the water inside the cell is hypotonic compared to the extracellular environment, then water will travel into the cell by osmosis. When the water inside the cell is hypertonic compared to the extracellular environment, water travels out through osmosis. If both areas are isotonic then both solutions will continue to remain balanced. If the salt solution concentration is increased, then the potato will experience a larger decrease in mass due to the occurrence of osmosis.
The dependant variable was the rate of osmosis measured by the average percentage change in mass. Observations: Texture of potato became spongier after the occurrence of osmosis. Water became slightly cloudy and starchier. The overall trend showed the salt solution with higher concentration to experience a greater rate of osmosis resulting in a larger decrease in mass apart from the end of the individual graph, which would suggest a random error to have taken place. Both sets of data showed solutions with higher concentration is hypertonic compared to the potato cells meaning the water would travel to the solution because it contained more salt. Evidently, the rate of osmosis in solutions with less salt were of a lesser extent because the water from the potato cells were less attracted.
Hence why both the individual and class data indicated a gain in the potato mass. These results were represented in the negative linear trend in the graph Figure Three. The osmosis practical posed no situation where the potato cell and solution were in an isotonic state, however, it could be predicted that no overall net movement would occur, and the potato mass would stay the same. It is important to keep all controlled variables the same across all salt solutions to produce accurate data.
If variables differ among the solutions then results would be influenced, producing inaccurate data. Various errors can be encountered in a practical way that can influence results, making them differ from the true answer. There were 10 sets of data undertaken that were all similar, comparing the individual data with the line of best fit from the class data Figure Five can show where random errors may have occurred.
If the entire set of data was to be moved but have a similar shape in the line of best fit, then it could be determined that a systematic error was of occurrence. A random error met was the slight difference in the size of potato cubes. A human cannot cut all potato cubes with precision, having the same weight and dimensions across all cubes. Although only a slight difference occurred with cubes ranging from 8. This could be improved by using technology that can be relied on to cut all cubes with precision. The accuracy of a human starting the stopwatch at the exact time the potatoes were submerged is unreliable because of their reaction time.
The inaccuracy of time can result in some cubes being submerged in the solution for longer and allows time for more osmosis to occur, meaning the mass will be invalid. For accurate timing, technology could be used to start and end exactly when the cubes are submerged and taken out. Another random error present was the excess water removed after the occurrence of osmosis. Drying the cubes with a paper towel could not be the same across all cubes and could remove different amounts of water from each cube.
This would change the mass because the cubes with less water soaked up, would have a heavier mass. The systematic errors encountered in the practical included the calibration of equipment such as the stopwatch under the assumption that it was already working, causing invalid data. Environmental effects such as the temperature of the lab, the potato cell concentration, and the potato age are systematic errors that can be present in the practical. It was determined by testing potato cubes in salt solutions with different concentrations, that when the salt solution concentration was increased, the potato experienced a larger decrease in mass due to the occurrence of osmosis.
The hypothesis was supported by the individual data Figure Two and where errors occurred, the true value was supported by the class data. Some limitations in the experiment were present such as the limited equipment such as technology that could have improved the precision, resulting in inaccurate data, and the inability to repeat the experiment, lowering the validity and reliability of the data gained.

The plus sign shows that it has gained mass. It will have gained water by osmosis. The minus sign shows that it has lost mass. It will have lost water by osmosis. Rachel carried out an experiment to investigate osmosis in potatoes. She placed five 3 cm cylinders of potato in five test tubes which contain the same concentration of salt solution. This is a section of the results table. Calculate the most accurate arithmetic mean from the results given.
Percentage change in potato mass. The most accurate arithmetic mean can be calculated like this. Accurate means close to the true value. The 34 per cent change in mass in Test 4 is an obvious outlier , and should not be included in the calculation of the mean to produce the most accurate result.Home Explore Potato experiment osmosis Signup.
