osmosis

• What is diffusion?

  Net movement of particles from high to low concentration
• What is osmosis?

  Diffusion of water molecules across a membrane
• What is the definition of osmosis?

  Net movement of water from high to low concentration
• What does water concentration refer to?

  Amount of water compared to dissolved solutes
• What are solutes in the context of water concentration?

  Substances like sugars or salts dissolved in water
• How does solute concentration affect water concentration?

  • Higher solute concentration means lower water concentration
  • Lower solute concentration means higher water concentration
• If one beaker has one solute particle and another has three, which has higher solute concentration?

  The beaker with three solute particles
• What determines the concentration of water in a solution?

  The proportion of water compared to solutes
• How does osmosis apply to cells?

  Water moves from high to low concentration across membranes
• What is found inside the cell in the osmosis example?

  Lots of water particles and some solute particles
• What is the water concentration outside the cell in the example?

  Higher water concentration with few solutes
• What happens to water particles in the osmosis process described?

  They diffuse into the cell from outside
