Osmosis is the process where water molecules move across a selectively permeable membrane from a region of lower solute concentration to a region of higher solute concentration. In the context of the experiments referenced, the observed changes are typically attributed to the movement of water and solutes, which aligns with the principles of osmosis. This movement is fundamental in maintaining cell turgor and overall homeostasis.
