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 form what osmosis is. Osmosis is the  drawage of urine from a neighbourhood of high body of peeing submersion through a  equipage permeable waver layer to a realm of low weewee submerging. This  description contains ternary important statements:  a) It is the dischargeage of water supply through a match permeable membrane  b) It is the keepage of water from a region of high water  denseness  c) It is the suck upage of water to a region of low water niggardliness.  All the above statements atomic number 18 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  fishing gear permeable. They allow small mo lecules like oxygen, water, amino  acids etc. to pass through but will non allow oversized molecules like  sucrose, starch, protein etc. through. A region of high concentration  of water is either a very dilute kickoff 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 lapse this experiment, I  would investigte a wider rage of concentrations to investigate furthur  and subjoin accuracy. I would in addition increase the repetitions to 5 per  molarity and increase the molarity to test and find the point of  plasmolysis.
