Cell Membrane Permeability Diagram - Water and Solute Diffusion Explained #3616149 (License: Personal Use)

This diagram depicts a phospholipid bilayer membrane separating two solutions: one with fewer solute molecules (left) and one with more (right). Gray circles represent water molecules, pink pentagons represent solute molecules, and the green-and-white structure is the hydrophobic-hydrophilic lipid bilayer. The image demonstrates principles of osmosis and diffusion in cellular transport.

Used in educational contexts-biology textbooks, classroom slides, or online learning modules-to teach membrane permeability, osmosis, and passive transport mechanisms. Matches user intent for visual aid in understanding basic cell physiology.
