After the experiment the students noticed that the potato stick with the lowest mass was soft and floppy. Explain why the potato stick had become soft and floppy.

Cells / potato sticks, have lost water (by osmosis) ; from high water potential to low water potential/down water potential gradient ; (cells / tissue/ potato) were, plasmolysed/ flaccid ; loss of turgor (pressure) ; not enough pressure of water pushing on cell walls ;
