Osmosis Explained: How Water Moves Through a Selectively Permeable Membrane #3616148 (License: Personal Use)

The diagram illustrates osmosis in action: a selectively permeable membrane separates a concentrated sugar solution (fewer water molecules) from a dilute one (more water molecules). Over time, water moves from the dilute side to the concentrated side-shown by red arrows-until equilibrium is approached. This passive transport process is fundamental in cellular biology and plant physiology.

Used in educational contexts-biology textbooks, high school/college lecture slides, and online science resources-to teach diffusion, osmosis, and membrane transport. Matches user intent for visual learners seeking clear, accurate explanations of passive transport mechanisms.
