Kyle Evers Relative Osmotic Concentration of Plant Cells Abstract—In the experiment we tested the relative osmotic concentration of potato slices. The actual concentration would have required us to factor in turgor pressure. Six slices, approximately 4cm in length and 2cm in width, were weighed and then placed in varying levels of sucrose solution. After soaking for an hour they were again weighed. Pending on the level of sucrose in each solution, the slices gained different amounts of water. Our null hypothesis was that the slices would gain the same amount of water even when placed in different sucrose concentrations. Our alternative hypothesis was increase in molar sucrose concentration would lead to lesser water gains. The results showed in lower sucrose concentrations the slices gained a greater amount of water than slices placed in higher sucrose concentrations. Introduction—Slices generally gain the most water when placed in a lesser concentration of sucrose. When slices are placed in pure water they jumped 18% in weight. In a sucrose
