Which part of the cell membrane is non polar and privets the cell from dissolving?

The non-polar part of the cell membrane is the lipid bilayer, primarily composed of phospholipids. The hydrophobic (water-repelling) tails of these phospholipids face inward, away from the aqueous environment, creating a barrier that prevents the cell from dissolving in water. This structure allows the membrane to maintain its integrity while regulating the movement of substances in and out of the cell.
