Exercise 1 – Potato Change in Mass versus Sucrose Concentrations Introduction: This exercise involves estimating the osmotic concentration of potato tuber cells by using a change in mass method. The null hypothesis states that there will be no change of mass of the potato disks after they have been incubated in any sucrose solution. This means that the concentration of sucrose that the potatoes are in will no effect the movement of water in or out of the potato cells. However‚ the alternative hypothesis

VII. Conclusion The hypothesis that if a potato is placed in a tube with different sucrose concentrations then the tube with the lowest concentration of sucrose will expand the potato the most because the water will move into the potato to even out the concentration levels of the sucrose/ water ratio inside and outside of the potato was supported by the data. The data shows that the potato submerged in the lowest concentration of the sucrose water solution had the greatest percent change in mass
