Investigating The Concentration Of The Solutions Inside The Vacuole Of A Potato Cell.
Osmosis Investigation
We are trying to find out what the concentration of the solutions is inside the vacuole of a potato cell.
We will investigate how the mass of the potato chips change in different sucrose solution concentrations.
We will use osmosis to do this.
I will be measuring and controlling many different variables, these include; -
The dependent Variable Weight of potato chip
Independent Variable Concentration of sucrose
Control Variables consist of; -
1. Temperature
2. Surface area of potato
3. Volume of sucrose solution
4. Same time for each potato chip submerged in solution
5. Potato chips all from same potato
The effects on the dependent variables all differ; here is how the main variables in my experiment work out.
Variable Effect on Dependent Variable
Surface area of potato chip The greater the surface area the more water it will be able to absorb
Same chip from the same potato The genetic make-up will be......
