Prediction Osmosis is defined as is the movement of water molecules across a partially permeable membrane from a region of high water concentration to a region of low water concentration. In a high concentration of water the amount of solute e.g. sugar is low. This could be called a weak or dilute solution. In a low concentration of water the amount of solute e.g. sucrose is high. This could be called a strong or concentrated solution. When two such solutions are divided by a semi-permeable membrane the water will move from the area of high concentration to the...
be prevented by amalgamating sets of results, for example of a whole class, where each experimenter used a different potato. I think that three sets of results was a good number. However, I think that in order to improve my results, the last concentration 1 moler needs to be retaken as it is an anomalous result.

Further work could be carried out to include concentrations that increased in 0.1 M rather than 0.2M. This would increase the accuracy and improve the graph. Other investigations could include using different varieties of potato or different plant tissues e.g. carrot.
