Answer: low solute concentration to high solute concentration
high solvent concentration to low solvent concentration
Step-by-step explanation:
Osmosis is defined as the process in which molecules of a solvent tend to move through a semipermeable membrane from a region of low concentration solution to a region of more concentrated solution.
For example, absorption of water by the roots of a plant is due to osmosis.
Also, low concentration of solute means high concentration of solvent, thus water is flowing from high concentration of solvent to low concentration of solvent.
Thus, we can conclude that in case of osmosis solvent molecules move from solution having low solute concentration to high solute concentration high solvent concentration to low solvent concentration
