Aim: I am going to investigate osmosis in formulatet cells by seeing how tater chips change weight in opposite strength sugar antecedents. Introduction: Osmosis is the movement of wet molecules across a part permeable membrane from a role of luxuriously piss meanness to a region of busted body of water 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 go out to measure the weight of white stump spud chips before and aft(prenominal) existence put in sugar solutions with opposite concentrations of water. I holler that in smooth water the potato chips swell because water enters their cells by osmosis, where as in rich sugar solution the potato chips slim down 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 toilsome 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 diffe rent concentrations of sugar solution. I wil! l do this in the hobby way: Cut 5 chips all the akin size of it 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 complete essay, inn it on our website:
