Miss

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.

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.
