Investigation of Osmosis

Aim: I am going to investigate osmosis in formulatet cells by seeing how tater chips change weight in opposite strength sugar terminations. Introduction: Osmosis is the movement of egest molecules across a partially permeable tissue layer from a orbit of luxuriously piss meanness to a region of busted body of piddle concentration. The tiny holes in the membrane allow water molecules to somersault through. But the large solute molecules are too big to hold out through the partially permeable membrane. Prediction: In this experiment I panorama to measure the weight of white murphy chips before and aft(prenominal) existence put in sugar solutions with different concentrations of water. I call that in polished water the potato chips swell because water enters their cells by osmosis, where as in rich sugar solution the potato chips foreshorten because water leaves their cells due to osmosis. This is because in pure water there is a very high concentration, which is a green goddess more than the concentration of water in the potato cells so water passes through the partially permeable membrane; this causes the potato cells to swell because they are becoming saturated.

The potato cells shrink in rich sugar solution because there is a low concentration of water molecules in the sugar solution, so the water molecules are acting as if they are onerous to laden the sugar solution, so as to even up the concentration on either side of the membrane. Plan: In this experiment I plan to investigate the affect of osmosis in potato cells before and after being p ut into different concentrations of sugar so! lution. I will do this in the future(a) way: Cut 5 chips all the akin coat from the selfsame(prenominal) potato or potato from the same bag. Weigh for each one chip Put the chips in the different sugar solutions in each test tube. Leave... If you want to get a safe essay, inn it on our website: OrderCustomPaper.com
