How does the mass and length of potato slice change when left in different concentrations of Sucrose solution?

Aim

The aim of the investigation is to see how the mass and length of potato slice change when left in different concentrations of Sucrose solution.

Background Knowledge

I know that Osmosis will be a big factor which will affect the length and mass of the potato slice. Osmosis is the flow of a substance through a semi-permeable membrane while the other substance is blocked and unable to pass through the membrane. I know that the water will travel both from and to the potato tissue. This process usually takes place along a cell wall. All this basically means is that only small particles are let through while larger ones are stopped.

Prediction

I predict that lower concentration of the sucrose solution the more water is carried using the process of osmosis. The potato tissues, being surrounded by a weak solution, will be most likely to swell up and become turgid, taking in all the water it can possibly take in.

Fair Test

To make this experiment a fair on I will have make
