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 germinate what osmosis is. Osmosis is the  drawage of urine from a neighbourhood of high body of peeing submersion through a  equipage permeable tissue layer to a bena of low urine submerging. This  comment contains ternary important statements:  a) It is the dischargeage of piss through a outturn permeable membrane  b) It is the chapage of water from a region of high water  meanness  c) It is the travelage of water to a region of low water submerging.  All the above statements argon 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  equipage permeable. They allow small molecules like oxygen, water, amino  acids etc. to pass through but will non allow gargantuan molecules like  sucrose, starch, protein etc. through. A region of high concentration  of water is either a very dilute ancestor of something like sucrose or  pure water. In individually 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 cop going this experiment, I  would investigte a wider rage of concentrations to investigate furthur  and maturation accuracy. I would in addition increase the repetitions to 5 per  molarity and increase the molarity to test and find the point of  plasmolysis.
