This chart will illustrate the process of osmosis and its biological significance.

Layout:

The chart can be a segmented diagram with arrows showing the movement of water molecules.

Sections:

1. Solutions:
   • Show two containers, labeled “Solution A” and “Solution B,” representing different concentrations of a solute (dissolved substance) in a solvent (usually water).
   • Solution A: Label it as “Low Concentration” (hypotonic solution) and depict it with few solute particles dissolved in the solvent (water).
   • Solution B: Label it as “High Concentration” (hypertonic solution) and depict it with many solute particles dissolved in the solvent (water).
2. Semipermeable Membrane:
   • Draw a selectively permeable membrane separating the two solutions.
   • Briefly explain that this membrane allows water molecules to pass through but restricts the passage of most solutes.
3. Water Movement:
   • Show water molecules moving through the semipermeable membrane from the low concentration solution (hypotonic) towards the high concentration solution (hypertonic).
   • Arrows should indicate the net movement of water molecules, which is always from low solute concentration to high solute concentration.

Additional Information:

•  includes insets depicting scenarios of osmosis in biological contexts:
  • Animal Cell: Shows an animal cell in a hypotonic solution. Water enters the cell, causing it to swell. If excessive, this can lead to bursting (cytolysis).
  • Plant Cell: Shows a plant cell in a hypertonic solution. Water moves out of the cell, causing it to shrink (plasmolysis). The cell wall in plants helps prevent excessive shrinking and bursting.
  • Osmosis in Plants: Briefly mentions the role of osmosis in plant functions like turgor pressure (supporting plant structure) and water uptake through roots.

Benefits:

This visual chart aids in understanding osmosis by showcasing the movement of water molecules driven by concentration differences. The inset scenarios highlight the real-world applications of osmosis in biological systems.
