Potato Tonicity Abstract: » The purpose of this lab is to determine the potato tonicity · By putting in sucrose concentration into various concentrations, and measuring the weight change of the potato The % weight change of the potato had gone through positive and negative values. The toncitity would be .35 M. Below .35 M would be hypertonic. Above .35 M would be hypotonic. The toncitity is determined to be in the X-axis of the graph. When the concration is low the potato weighed more. When the concetration is high the potato weighed less. Results: Sucrose causes weight change to potato's 0.1 0.08 0.06 0.04 0.02 5 0.1 0.2 0.3 .0.4 0.5 0.6 0.7 -0.02

Explanation / Answer

A dilute solution has a high water potential than concentrated solution thus water flows from dilute to the concentrated solution .The cell membrane is a semipermeable membrane .So when a cell is placed in pure water water will move across the cell making it swell.The cell becomes turgid.If the potato weight is increasing it is due to extra water it is carrying.When the sugar concentration is 0% the potato will gain mass because
there is a higher concentration of sugar inside the potato. The
potato will weigh more because the vacuole has gained water and become
turgid. It will be harder and won’t be floppy .

Similarly when the potao is placed in the When the concentration is 20% the potato’s mass will decrease because
the net movement will be from the potato to the sugar solution. The
stronger sugar concentration is outside of the potato so the vacuole
will become smaller and the potato will be flaccid, so it will be
floppy and soft.
