Seven 250­ml beakers were obtained and labeled with the following molarity of sucrose solutions: 0 M (pure water), 0.1 M, 0.2 M, 0.3 M, 0.4M, 0.5 M, and 0.6 M. 100 ml of each solution was added to the appropriate beaker. Then, a cork borer was used to obtain a potato cylinder from the potato. It was pushed through the longest axis of the potato. A punch was used to push the potato cylinder out of the cork borer. Enough potato cylinder was obtained to provide 7­ 1 cm sections. Care was taken to ensure the potato skin was cut off. Each potato piece was blotted dry with a paper towel. A plastic weight boat was placed on a scale, tared and set to measure in grams. Each potato piece was weighed, and the weight was recorded in a table. After weighing,

  • Measuring The Rate Of Osmosis In Potato Cells

    1995 Words  | 4 Pages

    Measuring The Rate Of Osmosis In Potato Cells Skill Area P. Osmosis is defined as free water molecules diffusing from a high concentration to a low concentration through a semi-permeable membrane. Variables - The rate of osmosis effected by many different living things, temperature of the solutions, surface area over which it can occur, Volume of solution, Volume of potato, distance through which the free water molecules have to pass and finally the difference in concentration of the solutions. This final factor is the one that we are going to test during the experiment. The temperature increase causes the cells to expand so the whole potato expands. Different volumes of potatoes at different temperatures could be measured, however trying to measure the temperature of a potato effectively without causing defects in other results would be quite hard with the equipment we are using.

    Conclusion In my conclusion, the potatoes with the lowest concentration gained the most mass, and would become hard relating back to the Turgor theory I stated earlier. In contrast to this, the potatoes in the most concentrated solution lost the most weight thus becoming plasmolysed and limp also relating back to the background I have mentioned earlier. Evaluation In general the experiment was succesful the results were consistent and also were in accordance with the theories made at the start.. The experiment could have been improved by: · More subjects used instead of potatoes · More potatoes · Wider time ranger · Different molarities Using this variety of methods could have improved the experiemnt, however I was generally satisfied with the results of this osmosis experiement.

  • Osmosis Essay

    1438 Words  | 3 Pages

    This occurrence can be explained through the process of osmosis. The increase in mass as well as the increase in turgidity, in the potato tubes immersed in low sodium chloride concentration solutions is understood to be a hypertonic. Since the solution is hypertonic, the water molecules will diffuse into the area of lower water concentration (the potato tube) in order to achieve equilibrium. Alternatively, the decrease in mass in the potato tube submerged in highly concentrated sodium chloride solutions can be explained by its immersion in a hypotonic solution. As sodium chloride solution is less concentrated in water molecules than the potato tubes, the decrease in mass and loss of turgidity results from the net movement of water leaving the potato tube, which is higher in osmotic pressure, and diffusing into the solution.

    Seven evenly cut pieces of potato cylinder were incubating in distilled water, 0.1M, 0.2M, 0.3M, 0.4M, 0.5M, and 0.6M sucrose solutions for 1.3 hours to test the effect of osmolarity on the potato tuber cell. The pieces were weighed and compared to the weight of the potato before the incubation. Each final weight of the potato cylinder decreased as the concentrations of sucrose became higher, and the change in weight of the potato decreased in the higher concentrations of sucrose. Within the incubation period, the water

  • Determining the Concentration of the Cell Sap in Potato Storage Tissue

    Determining the Concentration of the Cell Sap in Potato Storage Tissue Aim: To determine the concentration of the cell sap in potato storage tissue. By using Osmosis, determine what the sugar concentration of cell sap is. Prediction I predict that the potato segment in the distilled water will definitely gain in weight because the solution outside it has a much higher concentration of water then in the cell sap meaning Osmosis will occur and the potato segment take in water. I predict that 0.2M sugar solution will also gain weight because it still has quite a high concentration of water outside the potato. The potato in the 0.4M solution will gain weight but the potato in the 0.6M and 0.8M solutions will lose weight.

    We then cut our potato tubes with the cork borer and cut them with the scalpel so they were the same length and weighed them. We then put one potato tube in each test tube and then added the same amount sugar solution in to each tube. The concentration of sugar solutions varied in each test tube.

  • Systematic and Random Errors in an Experiment with Potatoes

    The biggest weakness was the fact that this experiment was not conducted several times to highlight the systematic errors and again, eliminate any random errors that can be avoided. Only a small range of sample size was taken and therefore, different concentrations outside the 0%-10% glucose solution should be tested to have a better understanding of the trend. Drying of the potato varies and this can cause a major effect on the after mass of potato cores.
