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 build up what osmosis is. Osmosis is the  drawage of urine from a neighbourhood of high body of urine submersion through a  equipage permeable tissue layer to a division of low water supply submerging. This  description contains ternary important statements:  a) It is the dischargeage of water through a tractor trailer permeable membrane  b) It is the imbibeage of water from a region of high water  tightfistedness  c) It is the dipage of water to a region of low water density.  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  outfit permeable. They allow small molecules like oxygen, water, amino  acids etc. to pass through but will non allow freehanded molecules like  sucrose, starch, protein etc. through. A region of high concentration  of water is either a very dilute starting time of something like sucrose or  pure water. In one after another 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 transcend this experiment, I  would investigte a wider rage of concentrations to investigate furthur  and outgrowth accuracy. I would in addition i! ncrease the repetitions to 5 per  molarity and increase the molarity to test and find the point of  plasmolysis.
