The Effect of Sucrose Concentrations on the Mass of a cellResearch question: How does sucrose concentrations effect the mass of a cell?Background information:Lab terms:Diffusion: a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration.Sucrose: is a disaccharide, consisting of two monosaccharides:glucose and fructose.The concentration gradient is the gradual change in the concentration of solutes present in a solution between two regions. Diffusion occurs when they are concentration gradient.Selectively permeable membrane: the membrane that will allow certain molecules or ions to pass through it by diffusion. Dialysis tubing is selectively permeable to sucrose.Plasma membrane is a biological membrane that separates the interior of all cells from the outside environment which protects the cell from its environment.Hypothesis: The 0M,0.2M and0.4M sucrose solution will let water pass into the cells, causing increase in cell mass. The 0.6M,0.8M and 1.0M will let water move outside the cells, causing decrease in cell mass. The concentration of sucrose outside the cells is less than the concentration inside the cells, so water flows into the cells (diffusion). The physical process of diffusion will occur as a natural response to the concentration gradients.
