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 machinate what osmosis is. Osmosis is the  drawage of urine from a neighbourhood of high body of pee supply submersion through a  equipage permeable wander layer to a orbit of low pissing submerging. This  comment contains ternary important statements:  a) It is the dischargeage of water through a rigging permeable membrane  b) It is the belongage of water from a region of high water  absorption  c) It is the straitsage of water to a region of low water niggardness.  All the above statements are included in the definition, but define  certain aspects of it.  Semi-permeable membranes are very thin layers of material which allow  some things to pass through, but prevent others. A cell membrane is  semi permeable. They allow small molecules like oxyge n, water, amino  acids etc. to pass through but will non allow gravid molecules like  sucrose, starch, protein etc. through. A region of high concentration  of water is either a very dilute stem of something like sucrose or  pure water. In one at a time 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 th! e  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 overlay this experiment, I  would investigte a wider rage of concentrations to investigate furthur  and increase accuracy. I would in addition increase the repetitions to 5 per  molarity and increase the molarity to test and find the point of  plasmolysis.
