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 formulate what osmosis is. Osmosis is the 
drawage of urine from a neighbourhood of high body of water submersion through a 
equipage permeable tissue layer to a region of low water submerging. This 
definition contains ternary important statements: 

a) It is the dischargeage of water through a outfit permeable membrane 

b) It is the passage of water from a region of high water 
concentration 

c) It is the passage of water to a region of low water concentration. 

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 oxygen, water, amino 
acids etc. to pass through but will not allow large molecules like 
sucrose, starch, protein etc. through. A region of high concentration 
of water is either a very dilute rootage of something like sucrose or 
pure water. In severally 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. In L...

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 extend 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. I...If you want to get a secure essay, order it on our website: Orderessay
