Osmosis

• What is osmosis?

  Movement of water across a membrane
• What factors affect the rate of osmosis?

  Concentration gradient, temperature, and pressure
• What is the process of investigating water potential?

  • Measure the mass change of cells
  • Use different concentrations of solutions
  • Determine the point of no mass change
• What is the significance of measuring change in mass in osmosis experiments?

  It indicates water movement in cells
• What is a calibration curve used for in osmosis studies?

  • To relate concentration to mass change
  • To predict outcomes of experiments
  • To standardize measurements
• What topic does "Cell Membranes" refer to in this context?

  Structure and function of cell membranes
• Why is it important to practice questions on cell membranes?

  To reinforce knowledge and understanding
• What are the key components of cell membranes that might be studied?

  • Phospholipid bilayer
  • Proteins (integral and peripheral)
  • Cholesterol
  • Carbohydrates (glycoproteins and glycolipids)
