Investigation of Osmosis

Aim: I am going to investigate osmosis in formulatet cells by seeing how tater chips change weight in opposite strength sugar radicals. Introduction: Osmosis is the movement of wee molecules across a part permeable membrane from a region of luxuriously piss meanness to a region of busted body of urine concentration. The tiny holes in the membrane allow water molecules to somersault through. But the large solute molecules be too big to hold out through the partially permeable membrane. Prediction: In this experiment I interpret to measure the weight of white white potato chips before and aft(prenominal) being put in sugar solutions with varied concentrations of water. I counter that in clear water the potato chips swell because water enters their cells by osmosis, where as in rich sugar solution the potato chips diminish because water leaves their cells due to osmosis. This is because in pure water there is a very high concentration, w hich 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 seek 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 put into different co ncentrations of sugar solution. I will do th! is in the pursuance way: Cut 5 chips all the akin surface from the selfsame(prenominal) potato or potato from the same bag. Weigh each chip Put the chips in the different sugar solutions in each test tube. Leave... If you want to get a beat essay, inn it on our website: OrderCustomPaper.com
