Title: The effect of sucrose solution on Dialysis Tubing and Potato cells
Introduction/Purpose: This experiment will explain the relationship between solute concentration and the movement of water though a selectively permeable membrane by the process of osmosis. There are two labs to this experiment, my group and I will test the osmosis in dialysis tubing and potato cells. ... For the dialysis tubing it will be the mass (g) and volume (ml) change in dialysis tubing, while Osmosis in potato cells will have mass (g) and length (mm) change in potato cells after approximately 24 hours. ... Knowing how osmosis work is crucial to our living because we will know how cells gain and lose water. ...

Osmosis in Dialysis Tubing
Molarity of Dialysis Tubing Initial Mass (g) +/-. ... 18 160 150 -10
Data collect on 12th and 13th of November
Osmosis in Potato Cells
Molarity of Sucrose solutions Initial Mass of Potato (g) +/- . ... Our hypothesis is supported for the osmosis in dialysis tubing. ... The only possible error on the osmosis in potato cell lab would be the measurement of potatoes. ... The osmosis in potato cells hypothesis was not supported but close.
