Osmosis Explained: How Water Moves Through a Selectively Permeable Membrane #198346 (License: Personal Use)

The image depicts a classic osmosis demonstration using two compartments separated by a selectively permeable membrane. On the left, a concentrated sugar solution (fewer water molecules, more solute) is shown; on the right, a dilute sugar solution (more water, less solute). Red arrows indicate net movement of water molecules from the dilute side to the concentrated side, equalizing concentration over time.

Used in educational biology or chemistry web pages to explain passive transport and osmosis; matches user intent for learning foundational cell physiology concepts.
