Osmosis Practical Report
Introduction:
To determine the biological changes that occur to potato cores over a period of time in different solutions of sucrose and to relate these changes to the phenomenon of osmosis.
Method:
We soaked several discs of potato cuted using a cork borer with around 1 centimeter of diameter and 2 milimeters of lenght into sucrose solutions with a different range of concentrations from 0 to 1.0M. Then we weighed all the potato cylinders on an electronic balance (see results) and recorded the results. We placed enough pieces of potato to cover the bottom of the petri dish and left them for 60 minutes. After this time we drained out the solutions from the petri dishes and carefully placed them in order of molarity on a paper towel.
We also measured the total mass of the discs in each solution after soaking in the solutions (see results).
Percentage change in mass of the potato is measured in each case and......
