Finding out the affect of different concentrations of sucrose solution

Finding bug out the affect of opposite meannesss of sucrose solutionon the plurality of white spud vine chipsIntroductionThe aim of this investigation is to see when osmosis occurs in tater cadres and whether anything happens to them when they atomic number 18 put indifferent concentrations of sucrose solution. I have to check mybackground knowledge to devise an experiment which will tell mewhether if different concentrations of irrigate molecules in a solutionwill affect the mass of plant cell when they argon put into it.Background knowledgeOsmosis is corresponding diffusion but only of water molecules and it onlyhappens when on that point are different concentrations of water molecules on each side of a selectively porous membrane.The selectively permeable membrane gaps are only fiddling enough to letwater molecules descend through and not double molecules such as sucrosemolecules.Water molecules from each side of the membrane always sack up to theother side. Wh en one side of the selectively permeable membrane has ahigher concentration of water molecules than the other, more watermolecules from the side containing a higher concentration of watermolecules will pass through to the side with a lower concentration ofwater molecules. slight(prenominal) water molecules from the side with a lower watermolecule concentration will pass to the other side because there areless of them.If the concentration of water molecules on either side of theselectively membrane is the same then the net electric current of water in eitherdirection will be the same. This results in no net flow ofwater-osmosis.An example of osmosis happening in a plant cell is when a potato chipis put into distilled water. The cell membrane of the potato cells isthe selectively permeable membrane amid the concentration of watermolecules inside the potato cells and the distilled water that isoutside of the potato cells. As the concentration of water moleculesis of a higher concen tration in the distilled water than inside thepotato, there are more water molecules going through the potatomembrane into the cell than water molecules from the inside of thepotato going through to the other side.This is because there are more water molecules in the distilled water.Therefore the net flow of water by osmosis is into the potato cells.As more water molecules pass into the potato cells, the va... ...Maybe next time I could roll each potato chip down thepaper towel once and blot the ends of them 2 times on the papertowel.To prove that my prediction is correct in any osmosis experiment, Icould do another experiment, which shows osmosis happening and why ithappens-different concentrations between a selectively permeablemembrane. The experiment is shown belowApparatus* 20cm in length visking tubing.* 20cm3 water* 10cm3 plastic syringe* testing thermionic vacuum tube systemTie a knot at the end of 20cm length visking tube that has been soakedin water. Put 3cm3 of strong sugar solution in the plastic syringe anduse that to partly fill the visking tube-it should be floppy. shopping centrethe visking tubing into a test tube containing water 20cm3 . Leave thevisking tubing in the test tube for about 30-45 minutes.You should record your observations of the visking tubing forrader itwas put into the test tube of water and after it had been left in thewater. Look for any changes in how it looks and feels. Is it turgid orflaccid?Referencescollins GCSE total revision Science by Mike Smith and Chris SunleyGCSE biological science second edition by D.G.
