Investigating the Effects of Sugar Solution on Potato Cells
Plan
When water passes from a less concentrated sugar solution to a more concentrated sugar solution, this is called osmosis. ...
For example:
The water inside the cell’s vacuole has a lower concentration of sugar and a higher concentration of water than the outside of the cell in the beaker where the sugar concentration is high and the water concentration is low. These factors allow osmosis to occur from the inside of the cell to the outside in the beaker.
Osmosis can be stopped by osmotic pressure (OP) being applied. Stronger sugar solutions require more osmotic pressure to prevent osmosis. ...
Here are two example diagrams of osmosis in and out of a cell:
Weak Strong
If we made a range of different sugar solutions with a different concentration of sugar and work out their Osmotic Pressure, we could use these solutions to find the Osmotic Pressure needed to prevent osmosis in potatoes. ... 71
This preliminary test will help us find the breakeven point, when the OP of the cell is the same as the water around it. ...
I predict that the potato pieces which have been placed in the solution with the lower concentration of sugar, due to water moving out of the cell the mass of the potato will decrease.
