This demonstration provides an excellent example of how eukaryotic cells are compartmentalized and how important the bilipid layer of the endomembrane system is in providing this sectioned architecture. This demonstration also effectively depicts how lipid barriers exhibit a hydrophobic response to polar substances such as the cytoplasm and the nucleoplasm. By disrupting the various membranes during the demonstration, students can observe the amphipathetic nature of the membranes. Although this is not a true lipid bilayer, the characteristics of the lipid fluidity in membranes is clearly exemplified.
