osmosis

• What is diffusion?

  Diffusion is the net movement of particles from an area of higher concentration to an area of lower concentration.
• How do oxygen and glucose molecules move into a cell?

  They diffuse down their concentration gradient into the cell.
• What is osmosis?

  Osmosis is the diffusion of water molecules across a partially permeable membrane.
• What is the definition of osmosis?

  Osmosis is the net movement of water molecules from a region of higher water concentration to a region of lower water concentration.
• What does the term "water concentration" refer to?

  Water concentration refers to the amount of water compared to other dissolved molecules like sugars or salts.
• What are solutes?

  Solutes are the molecules like sugars or salts that are dissolved in water.
• How does the concentration of solutes affect water concentration in a solution?

  • Higher solute concentration means lower water concentration.
  • Lower solute concentration means higher water concentration.
  • It's the proportion of water to solutes that determines concentration.
• If one beaker has one solute particle and another has three, which has a higher solute concentration?

  The beaker with three solute particles has a higher solute concentration.
• What happens to water concentration when solute concentration increases?

  Water concentration decreases as solute concentration increases.
• How does osmosis occur in cells?

  • Water moves from an area of higher water concentration to lower water concentration.
  • Inside the cell has more solute particles than outside.
  • Outside the cell has higher water concentration.
• What is the role of the cell's partially permeable membrane in osmosis?

  The membrane allows water to diffuse while restricting solute movement.
• What is the result of water diffusing into a cell during osmosis?

  Water particles move into the cell from a region of higher water concentration.
• What is the main difference between osmosis and diffusion?

  Osmosis specifically refers to the diffusion of water molecules.
