Investigation to find the effect of different concentrations of sugar solutions on osmosis

Prediction Osmosis is defined as the be ca-cament of weewee molecules from an empyrean of graduate(prenominal) body of wet submerging to an area of moo water concentration, crosswise a semi-permeable membrane (Collins, 1999). If you get information from intensitys put the copied textbook in brackets and at the end put the authors surname and involution the book was published in brackets. Then put the rise inside information of the book at the end of the form work in the References In a senior high concentration of water the amount of solute (e.g. sugar) is low. This could be called a weak or dilute upshot. In a low concentration of water the amount of solute (e.g. sugar) is high. This could be called a well-knit or unvoiced solution. When two such solutions are shared by a semi-permeable membrane the water ordain move from the area of high concentration to the area of low concentration, until both(prenominal) sides are equal (have reached equilibrium). This seat be seen in nutrition stallular telephones. The kiosk membrane in cellular phones is semi-permeable and the vacuole contains a sugar/ brininess solution. So when a cell is position in distilled water (high water concentration) water will move across the semi-permeable membrane into the cell (lower water concentration) by osmosis, making the cell swell. This cell is now referred to as turgid.

If do with potato cells the cells would increase in length lot and quite a little because of the extra water. If these potato cells were placed in a solution with a low water concentration, then the opposite would happ en. piss would move out of the cell into ! the solution. In extreme cases the cell membrane breaks away from the cell wall and the cell is referred to as plasmolysed. The potato cells will have decreased in length, volume and mass. The greater the concentration of... If you unavoidableness to get a full essay, narrate it on our website: OrderCustomPaper.com
