Osmosis

• What type of process is osmosis?

  Osmosis is a passive process.
• What is osmosis a special type of?

  Osmosis is a special type of diffusion.
• What does osmosis involve the movement of?

  Osmosis involves the movement of water or water molecules only.
• In which direction does water move during osmosis?

  Water moves down a concentration gradient.
• From where to where does water move in osmosis?

  Water moves from a dilute solution to a concentrated solution.
• What type of membrane does osmosis happen through?

  Osmosis happens through a partially permeable membrane.
• What is the definition of osmosis?

  • A net diffusion of water
  • From a dilute solution to a more concentrated solution
  • Through a partially permeable membrane
• Why is osmosis important in animal cells?

  Osmosis ensures tissues obtain the right concentration inside the cell.
• What is a hypotonic solution?

  A hypotonic solution is more dilute than the cell's internal environment.
• What is an isotonic solution?

  An isotonic solution has the same concentration as the cell.
• What is a hypertonic solution?

  A hypertonic solution is a more concentrated solution.
