Potato Mini-lab- What and why has it occured?
Our group figured out that the potato slices were placed into two different liquids, because one had a rough, stiff shape, while the one in the other beaker has a smooth, flexible shape. So, we concluded the the harder potato slice was placed into tap water, while the softer potato slice had been placed into salt water. What happened with the smaller potato slice is that because the concentration of water molecules inside the cell was greater than in the salt water, osmosis occurred and the water molecules in the higher concentration were tranported to the lower concentration of molecules, effectively shrinking the cell because of its loss of water. For the other beaker, what happened was because the higher concentration of water molecules were in the water outside of the potato, the molecules in the water transported to the ones in the cell, effectively causing the cell to swell because of its increase in water.
