Diffusion and Osmosis: Potato core lab/ Agar lab | …
v The potato cores all had different levels of moisture at the start
of the experiment, meaning that some potato cores would need less
osmosis to reach equilibrium within the same molarity solution.

This also means that the 0.6
to 1.0 potato cores cannot absorb as much and therefore osmosis occurs
in the opposite direction, the potato core losing water to the
ap lab1 osmosis sample 3 - Biology Junction
We are weighing potato cores for their initial mass and then we are waiting for a time period of 24 hours too check the final mass to see if they were to lose of gain weight from the sucrose solution.
If the potatoes are hypotonic to the solution then they will lose mass.
Lab 1: Diffusion and Osmosis | Spurthi's AP Biology …
The initial mass decreased over the time period of 24 hours because the weight of the potato cores all mostly lost weight except for one in the .2 sucrose solution.
Diffusion and Osmosis Lab – Biology Tea
* Concentration of water in the potato - The higher the concentration
of water already in the potato, the quicker osmosis will occur because
less water will have to diffuse into the potato to even the amounts of
water inside and outside of the potato cells.

At this point there will be
no change in the length, volume and mass of the potato, as the net
movement of water will be zero, no more osmosis has occurred except to
keep the levels of water approximately balanced.
