I predict that the stronger the solution of sucrose the more mass the pieces of potato will loose. This is because the solution will be more concentrated than the solution in the potato. So the water in the potato will come out through the partially permeable membrane of the potato cells into the more concentrated sucrose solution. This means that the mass of the potato will decrease because the water from the solution will have moved out of the potato into the sucrose solution. When the concentration of the sucrose solution is weak (weaker than the solution inside the potato) the potato will gain mass. This is because the solution in the potato is more concentrated than the sucrose solution. So the water in the sucrose solution will soak into the potato by passing through the partially permeable membranes of the potato cells because the potato is more concentrated than the sucrose solution. This means that the potato will gain mass because the potato now h

In each petri-dish I put 1 piece of potato, which was labelled, weighed and the put lid on and then left for 12 hours. Then after 12 hours I weighed the potato pieces making sure there was no excess solution on them and repeated the experiment another 2 times. This allowed me to work out averages so that my results were very accurate.

as more water in it. This is all because in osmosis the partially permeable membrane in plant cells will allow the water in the less concentrated side to seep through to the more concentrated side.
