A highly detailed, scientifically accurate cross-section of a biological cell membrane (lipid bilayer) on a white background, ultra-realistic 3D illustration. Show the phospholipid bilayer with hydrophilic heads (round, polar) facing outward and hydrophobic tails (chains) inside. Include embedded proteins (integral and peripheral), cholesterol molecules (small, rigid), glycoproteins with sugar chains, and ion channels. The style should be clean, lab-textbook style, with subtle shadows and depth. Use a color scheme: light blue for hydrophilic heads, yellow for hydrophobic tails, red/pink for proteins, and orange for cholesterol. Microscope-like precision, no artistic stylization. Educational diagram of the Fluid Mosaic Model, cross-sectional view with labels for 'glycoprotein', 'cholesterol', and 'peripheral protein', vector graphic style.emoji
