Find the concentration of sucrose in a potato cell - Plan :: GCSE Biology A2 A-Level Coursework

Find the dousing of sucrose in a potato cell - picturePlan For Osmosis/Plasmolysis ExperimentAIMIn this experiment, I am trying to find the concentration of sucrosein a potato cell. Also I can observe when a cell is totallyplasmolyised.PLANI plan to complete this experiment within an hour. Firstly, I will cut 15 potato chips, 3 each for 5 incompatible solutions, each measure 1.2grams, cut with a 4mm corer to approx (full word) 4cm. I will measure weight, as length is slight accurate. The weight of the chip may vary as much as 0.02 g each way, which will make it a lot easier to do, but may provide me with less accurate results. I will use 5 different molar solutions of 20 cm3 each, shown to the right. 0M (water), 0.5M, 1M, 1.5M and 2M. I will create 0.5 molar solutions by mixing 10cm3 of water and 10cm3 of 1 molar solution. I will use 3 of each solution to ensure that my results are correct, and to prevent any anomalies unreassuring my result graphs. One of each solution will be dropped into the solution at 10-secondintervals. They will be taken out 30 minutes after precisely, toensure a reliable result. They will then be dried on a paper towel,and quickly weighed, and recorded in a pre-written table. dependability/ FAIR TESTI must control many variables in this test. I will control the timethat they are left in the solution, as this will greatly affectresults if they are left in for different amounts of time. Also I mustcontrol how much I dry the chips in front weighing them, because if Ileave some excess water on one of them, it will be an unfair test, asill be weighing the water as well as the chip. Another point issimple, but just to make sure that the scales I am weighing the chipon are at 0 before weighing the chip, as it may add some mass to thechip. I will use 5 different solutions, starting at 0 molar and goingup in 0.5 molar concentrations. I have chosen this because they areequidistant, allowing for easy graph drawing, and as well because fr omthe preliminary experiment, I know that this will give me results thatcan show me the concentration of sucrose in the cells sap, and also goon to show me the concentration that the cell will plasmolyise at. Iwill also control the variety of potato- I will only use 1 brand, as
