the process called osmosis in which plant cells take up water and they start to swell, but the cell wall prevents them from bursting.

At point A the graph tells the viewer that no osmosis has occurred, suggesting that the concentration of water inside the cell is equal...

GCSE Biology: Osmosis in a Potato
Aim
To investigate the effect of placing a piece of potato in a given strength of sugar solution.
Prediction
I predict that, as...

I am going to record my results to see if osmosis occurs in water solution of sugar solution.
Apparatus
In this experiment...
Many cell membranes behave as semi permeable membranes, and osmosis is a vital mechanism in the transport of fluids in living organisms, for example...

Quality of Results
Were your results of a good quality? How...
partly permeable membrane from a high to low concentration of water osmosis is just an special kind of diffusion because only the water molecules and their movement...

The aim of this investigation is to compare & evaluate the effects of osmosis in potato chips. We aim to find out the different outcomes that can (and will...
time that I used for the experiment to last was enough to allow sufficient osmosis to occur. However if I was to repeat the experiment I might well increase the time...
the potato chip compared to the water molecules in the surrounding solution so osmosis again occurred making the water molecules move from the solution to the potato...

Some of the weaknesses of this experiment were that the process involved in removing the surplus...
Right equipment
A different experiment to this can be seeing if heat affects the process of osmosis. Or we can use salt solution instead of sugar solution and see...

the mass wont change. Finally the sucrose will play no part in the osmosis, this is because the sugar particles are to big to fit through the semi-permeable membrane...
