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 muse what osmosis is. Osmosis is the drawage of urine from a neighbourhood of high body of pissing submersion through a equipage permeable tissue paper layer to a section of low irrigate submerging. This comment contains ternary important statements: a) It is the dischargeage of piddle through a dress permeable membrane b) It is the proceedage of water from a region of high water preoccupation c) It is the take backage of water to a region of low water submersion. All the above statements ar included in the definition, but define certain aspects of it. Semi-permeable membranes ar very thin layers of material which allow some things to pass through, but prevent others. A cell membrane is carriage permeable. They allow small molecules like oxygen, water, amino acids etc. to pass through but will not allow braggy molecules like sucrose, starch, protein etc. through. A region of high concentration of water is either a very dilute source of something like sucrose or pure water. In one by one 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.

To 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 snuff it this experiment, I would investigte a wider rage of concentrations to investigate furthur and step-up accuracy. I would in addition increase the repetitions to 5 per molarity and increase the molarity to test and find the point of plasmolysis.
