Biology Experiment on Osmosis for GCSE

Conclusion:
From all these facts and figures we can ascertain that osmosis has taken place because it has a semi-permeable membrane. As quoted in the hypothesis, the solution is stronger than the isotonic solution then the cell will lose water.
The amount of water in the cells of a potato has an effect on its isotonic solution. The isotonic solution of the potato in this experiment was 0.08. The results showed that as the strength of the solution increases the % mass difference falls.
Water has left the cell to go and try to dilute the stronger solution that is outside the cell. It has tried to make the concentration gradient the same. As the strength of the solution increases, the more water leaves the potato. The potato cell has a cell wall, however, so the cell has only become dehydrated or plasmolysed to a certain extent because of this unlike animal cells.
The prediction of a change, for higher and for lower, at about 0.4 on the concentration solution was not close, but, as the results of the experiment show, that it was inaccurate by 3.8 molar. Perhaps the water potential of the particular potatoes was slightly higher than average. Even though the prediction was inaccurate i can deduct that it was a highly successful experiment.
