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.
Nonpolar fatty acid chains are nonpolar and prevent the cell from dissolving.
Fatty acid chains
The lipid bilayer prevents the cell from dissolving in water.
Nonpolar Fatty Acids
The part of the cell membrane that is nonpolar and prevents the cell from dissolving is the phospholipid bilayer. This bilayer consists of hydrophobic (water-repelling) fatty acid tails that face inward, away from water, while the hydrophilic (water-attracting) phosphate heads face outward towards the aqueous environment. This arrangement creates a semi-permeable barrier that maintains the integrity of the cell by preventing the free passage of water-soluble substances.

Nonpolar fatty acid chains are nonpolar and prevent the cell from dissolving.
Cell membrane have proteins embedded in them that act as channels for things to enter and leave the cell. Furthermore, the fact that the membrane is non-polar will block any polar molecules from entering but will allow non-polar molecules such as hormones to enter.
Yes, polar molecules can cross the cell membrane through facilitated diffusion or active transport.
Fatty acid chains
Yes, polar molecules can pass through the cell membrane with the help of specific transport proteins.
The Cell membrane, along with its integrated proteins. In prokaryotes the Cell membrane is bolstered by the [mostly cellulosic] Cell Wall; in eukaryotes the Cell membrane is bolstered by the [glyco-protein] Cell Coat.
The lipid bilayer prevents the cell from dissolving in water.
Yes, small polar molecules can cross the cell membrane through a process called passive diffusion.

It's called membrane potential.
