Osmosis Process Diagram - Solvent Movement Across Semi-Permeable Membrane #198354 (License: Personal Use)

The image depicts a classic osmosis demonstration: two compartments separated by a semi-permeable membrane, with pink circles representing solvent molecules and larger purple circles representing solute particles. Initially, the left side has higher solvent concentration; over time, solvent moves rightward, diluting the solute-rich side and increasing its volume. The final state shows a higher fluid level on the right, illustrating net solvent flow until equilibrium or pressure balance is reached.

Used in educational contexts-biology textbooks, online science courses, and classroom slides-to explain passive transport, cell membrane function, and tonicity. Matches user intent for visual learning of diffusion-related processes like osmosis and dialysis.
