Osmosis

    Cards (11)

    • What is osmosis?
      Movement of water across a membrane
    • How does osmosis relate to diffusion?
      Osmosis is a special case of diffusion
    • What type of membrane is involved in osmosis?
      Partially permeable membrane
    • What can pass through a partially permeable membrane?
      Only tiny molecules like water
    • What happens to water molecules during osmosis?
      They pass both ways through the membrane
    • Why is there a net flow of water into the stronger sugar solution?
      There are more water molecules on one side
    • What does osmosis do to the concentration of a strong sugar solution?
      It makes the solution more dilute
    • What is the overall effect of osmosis across the membrane?
      It tries to even up the concentration
    • What is the definition of diffusion?
      Passive movement of particles from high to low concentration
    • What are the key characteristics of osmosis?
      • Movement of water molecules
      • Across a partially permeable membrane
      • From higher to lower water concentration
      • Passive process
    • How does osmosis affect plant tissue?
      • Water movement into cells
      • Can cause turgor pressure
      • Affects cell rigidity and structure
