Investigation to determine if different concentrations of sucrose solutions affect osmosis in potato cells

The aim of this experiment is to investigate different concentrations of sucrose solutions and eventually determine the molarity of the cells inside the potato.

Osmosis is the process by which water molecules move from an area of low solute concentration to an area of high solute concentration through a semi-permeable membrane.

From this experiment I also hope to be able to find the isotonic point, the point where the mass and the length have not changed from how they were at the start of the experiment. This will enable me to find out the molarity of the potato cells.

Equipment list for this experiment:

* Potatoes

* Sucrose solutions

* Distilled water

* Scalpel

* Ruler

* Test tubes

* Test tube rack

* Pipettes

* Square tile

* Potato corer

Once this equipment has been gathered, I will carefully cut 9 cylinders out of the same potato, because different potatoes may be slightly different. These will then be carefully measured and weighed to ensure that
