Explain the process of osmosis.

Explanation should include

  • the definition of
    • osmosis
    • solute
    • solvent
    • solution
  • a discussion on the diffusion of water molecules from an area of high to low concentration through a semi-permeable barrier such as the cell membrane
  • osmotic pressure and the results of different types of solutions (e.g., hypertonic, hypotonic, isotonic). 

Process/Skill Questions:

  • What is a concentration gradient?
  • How does osmosis affect the life of a plant?
  • What is turgor pressure?
  • How does turgor pressure affect the outward appearance of a plant (turgid/flaccid)?
  • What is plasmolysis?
  • How can plasmolysis impact plant production?
  • How is osmosis used by cells?
  • What is the function of membranes in osmosis?
  • How do solute and solvent concentrations affect osmosis?
  • What is plasmolyzation?
  • How does saturation affect osmosis?
  • How are diffusion and osmosis different?
