Answer:
Osmosis is the movement of water molecules from a higher water potential to a lower water potential across a partially permeable membrane.
Please note two things:
- Higher water potential = High amount of water= low concentration of solute
- Lower water potential = Low amount of water = High amount of solute.
Now, If you want the definition in terms of solute concentration, it should be:
Osmosis is the movement of water molecules from a Low concentration to a high concentration across a partially permeable membrane.
Also, Note that no energy is required for this process.
