... ). At this point there will be no change in the length, volume and mass of the potato, as the net movement of water will be zero, no osmosis has occurred. In my table of results the trends that appear on my graphs and tables are quite similar. I recorded two sets of results both using the same equipment and using the same approach to find the ... , King Edwards etc could be used to see if the potato type actually matters when doing this investigation. Instead of just putting one potato in the test tube we could put three, as it should give you a better set of results and accurate graphs. ...

... is necessary to determine which membranes permit selective flow, or osmosis, because not all membranes act in this way. Many membranes allow all or none of the constituents of a solution to pass through; only a few allow a selective flow. As the potato is a plant cell, it contains a vacuole and a ... as fair as possible), and I will then weigh them and record the results. These will then be put into tables and will be used in graphs. I will also measure the temperature in the room. I am going to do the experiment three times, in each solution, and I will ... the equipment I am going to...

... is increased and as the concentration becomes higher the loss in mass becomes greater because they are not accurate enough to prove this true. The two different graphs (one of change in mass and the other of percentage change) both give very similar best-fit lines. The only difference is that one results shows raw data and the other processed results, so it ... and recorded the weights. 7. I swiftly put 3 potato chips into each beaker and then started my stopwatch. 3 chips were used to create an average which gave me a better set of results and more accurate graphs. 8. Whilst waiting I ...

... line graph which shows the 1st set of percentage results. I've drawn a line graph to show the 2nd set of results. I've drawn another line graph which shows the 1st set of percentage results. There is a definite relationship between the two sets of data that I used to plot the 2 sets of graphs. To conclude this, I can say that the movement of water through a permeable membrane is affected ... by the amount of sugar. The higher the amount of sugar, the more the potato chip will lose its weight. This ... two reasons: 1. The results follow my prediction. 2. All the points on the graphs are...

... in size. This is because the cell is fully plasmolysed and no more water can leave the cell. Apparatus For the experiment you will require: Cylinders of potato with a diameter of 6.5mm a borer with a diameter of 6.5mm Sucrose solution of varying strengths (ranging from 0M to 1M) A burette to measure out the sucrose solution. Six jar specimen bottles Razor blade Method We take a cylinder ... contract in strong solutions (low water concentration). This is due to osmosis, where water passes from weak solutions to strong solutions across a semi-permeable membrane, such as a cell membrane. T...
