Experiment to investigate the plasmolysis rate and concentration of sucrose solution in the onion cell
Neena Kim SFC1A
Date of the experiment : 1st September 2001
In the onion cell, there is cell sap which has a certain concentration of materials. Depending the concentration of the outside of the cell, the cell can be plasmolysed at the different rate by osmosis.
The cells will be plasmolysed more as the concentration increases. And incipient plasmolysis is the point when 50% of the cells are plasmolysed.
Around 0.35M point, the rate of plasmolysis is the greatest.
6 petri dishes
6 test tubes
test tube rack
six 10cm graduated pipettes
