Osmosis Coursework
INTRODUCTION:
Osmosis is the diffusion of water down its concentration gradient. A partially permeable membrane is a membrane with tiny holes so small that only water molecules can pass through.
AIM:
I am trying to find out the sucrose concentration inside potato cells
Low H2O High H2O
I will be finding out how the movement of water levels from high to low affects the weight of potatoes, if there is no change in mass then there is no osmosis - equal amounts of sucrose inside and outside the potato, if there is a change in mass then there is more sucrose inside of the potato than inside it, then osmosis occurs.
PREDICTION:
I predict that there will not be an increase in mass in the potato which means that osmosis has not taken place.....
