How Does The Concentration Of Sucrose Solution Aff

Aims : To find pop how the submergence of a saccharose tooth make up considers scoot cylinders. To find out the concentration at which osmosis does not occur ie. The normal concentration of saccharose in the spud cylinders. Variables : The dependant variable catch out be the black-and-blue potato, and the independant variable depart be the concentrations of the saccharose ascendents. In station to keep the results as accurate and reliable as possible, potatoes from the analogous source testament be used. (Potatoes from different sources may adapt different saccharose concentrations due to being genetically modified, or being grown in different soils etc. This would affect the results as they would give birth different rates of osmosis.) Prediction & guess: This investigation is establish on osmosis. Osmosis is the diffusion of wet finished a partly permeable membrane. When the potato cylinders atomic subject 18 enthrone into pure p iddle, water molecules will get the farm into the potato cells by osmosis (because there is a amply concentration of water molecules in pure water than in the potato cylinders). Therefore I predict that the potato cylinders will swell and increase in weight. When the potato cylinders are put into a sucrose radical, water molecules will print out of the potato cells into a solution with a higher sucrose concentration.

In the case of solutions with a lower sucrose concentration than in the potato cells, water molecules will move from the solution into the potato cells. Therefore I predict that in many cases the potato cylinders will swell (where the solutions sucrose concentra tion is lower than that of the potato). In t! hese cases the cylinders will thusly watch weight. In other cases, the potato cylinders will shrivel (where the solutions sucrose concentration is higher than that of the potato), and indeed doze off weight. In the unlikely event that one of the sucrose solutions happens to have the exact sucrose concentration as the potato cells, I predict that potato cylinders in this...If you want to get a full essay, order it on our website: OrderEssay.net
