An investiagtion to establish the isotonic point of potato cell sap
e the effects of osmosis on potato cell sap. I will test potato cylinders in different strengths of sucrose solution and record any results in a table. I will then analyse my findings and work out the ... engths and masses of the potatoes, with the water diffusing into the potatoes at a high rate in the sucrose solution and therefore making their size bigger than at the start. As the distilled water so ...

Osmosis
How does different concentration of sucrose solution affect the movement of a solution through osmosis?Background InformationOsmosis is ... O2, H2O, Nh2 (amino acids), C6H12O6 (glucose). But will not let larger molecules in like C12H22O11 (sucrose), Ch2O (starch) and protein. If the solution contains a higher concentration than the cell, ... ction is, because the concentration will be higher than the water in potato and it is going to be a sucrose solution. I know that sucrose can't be absorbed by osmosis, because it's too bigger molecule ...
