Here's how it works:
* Osmosis is the movement of water molecules across a semipermeable membrane from a region of high water concentration (low solute concentration) to a region of low water concentration (high solute concentration).
* This movement continues until the concentration of water molecules is equal on both sides of the membrane.
* Think of it like this: water wants to even out the "crowdedness" of solute molecules on either side of the membrane.
Key Points:
* Semipermeable membrane: This membrane allows some molecules to pass through but not others. In the case of osmosis, it allows water molecules to pass through but blocks larger solute molecules.
* Concentration gradient: This is the difference in concentration of water molecules on either side of the membrane. It's what drives the movement of water.
Examples of osmosis:
* Water moving from the soil into the roots of a plant.
* Water moving from the bloodstream into cells.
* Water moving from a glass of water into a concentrated salt solution.
