An experiment to investigate the equivalent molarity of potato tissue compared to sucrose solutions. Plan Osmosis occurs across a semi-permeable membrane where there is a difference in concentrations on the two sides of the membrane, and knowing that the cells will either become turgid (when water passes into them)or plasmolysed (when water passes out of them) and will therefore alter their volume. Our aim is to try and find out the equivalent molarity by the change in length of a potato chip when submerged in sucrose solution. Prediction We have studied turgidity and plasmolosis in a text book (biology for life) and in a preliminary experiment, where we tested osmosis on onion cells and saw them become turgid or plasmolysed. Although, we used only 2 concentrations. Quite simply one solution to turn it turgid and the other plasmolysed, and did not actually measure the amount of concentration or expansion. Therefore my prediction is that...
