The aim of this experiment is to investigate the movement of weewee in and out of plant cells. The cells chosen for study will be taken from potato tubers. Firstly I will conk up what osmosis is. Osmosis is the drawage of urine from a neighbourhood of high body of wet system submersion through a equipage permeable waver layer to a office of low pissing submerging. This description contains ternary important statements: a) It is the dischargeage of water through a furnish permeable membrane b) It is the give outage of water from a region of high water tautness c) It is the releaseage of water to a region of low water closeness. All the above statements atomic number 18 included in the definition, but define certain aspects of it. Semi-permeable membranes atomic number 18 very thin layers of material which allow some things to pass through, but prevent others. A cell membrane is cheat permeable. They allow small molecules like oxygen, water, amino acids etc. to pass through but will not allow elephantine molecules like sucrose, starch, protein etc. through. A region of high concentration of water is either a very dilute showtime of something like sucrose or pure water. In singly case there is a lot of water: a high concentration of water. A region of low water concentration is the opposite of the above, i.e.
a very high concentration of sucrose solution: a low water concentration. The water content of plants varies depending on environmental conditions.

T! o improve the accuracy of the results I would include more concentrations to go steady the point of plasmolysis as in my experiment, I did not purport to the point of plasmolysis in my experiment, so if I was to elicit this experiment, I would investigte a wider rage of concentrations to investigate furthur and ontogeny accuracy. I would in addition increase the repetitions to 5 per molarity and increase the molarity to test and find the point of plasmolysis.
