The non-polar reason is probably what's responsible for the more or less circular shape of a cell without loose ends (not counting examples where the cytoskeleton gives the cell a characteristically different shape, just as in neurons). It's the configuration that the cell can take which requires less energy to be in.
Besides that, in the non-polar region non-polar proteins are located, some important in metabolism and signalling.
Also, this layer filters out polar elements on either side, making the membrane selectively permeable.
What else can I help you with?
How are proteins positioned within the membrane?
The protein is anchored into the membrane by its nonpolar region, but the protein remains moblie. To explain it more, the middle section of the protein is made of many nonpolar amino acids. This nonpolar coil fits into the nonpolar interior of the lipid bilayer allowing the protein to float in the membrane.
Which part of the cell membrane is nonpolar and prevent the cell from dissolving?
Nonpolar fatty acid chains are nonpolar and prevent the cell from dissolving.
Which molecules difuse through the lipid portion of the plasma membrane?
Only nonpolar (hydrophobic) molecules can pass through the bi-lipid membrane. For example, hormones are nonpolar, and they can pass through the membrane.
In the plasma membrane why is the nonpolar attracted when opposites are supposed to attract ie polar and nonpolar?
I can only answer the second part of your question. As far as attraction goes, polar is not the opposite of nonpolar. Polar in itself has two opposites: positive and negative. Those two are the opposites that attract; a positive region of a polar molecule is attracted to the negative region of another polar molecule.
Do Hydrophobic molecules pass through the fatty-acid region of the plasma membrane easily?
Yes, hydrophobic molecules pass through the fatty-acid region of the plasma membrane easily due to their similar hydrophobic nature. The nonpolar tails of the phospholipids in the membrane provide a favorable environment for hydrophobic molecules to move across.
Can nonpolar molecules cross the cell membrane?
Yes, nonpolar molecules can cross the cell membrane through simple diffusion.
What is a nonpolar tail?
A nonpolar tail is a hydrophobic region of a molecule that lacks charged or polar groups. Nonpolar tails are often found in molecules such as phospholipids, where they cluster together in the interior of the cell membrane away from water.

How do nonpolar regions of a membrane proteins cause proteins to be held in the membrane?
IB sucks

Why do small nonpolar molecules cross a membrane?
Small nonpolar molecules can cross a membrane easily because they are able to pass through the lipid bilayer of the membrane due to their size and lack of charge, allowing them to move freely across the membrane.
Hydrophobic interactions of the tails of phospholipids can produce a. a cytoskeleton. b. a protein membrane. c. a nonpolar membrane. d. a lipid bilayer. e. hydrolysis of the fatty acid?
a lipid bilayer
What kind of particle would move through a cell membrane the easiest- small or large-polar or nonpolar?
Small and nonpolar.
What assists the movement of polar molecules across the membrane A. Passive Transport B. Active Transport?
Polar molecules must pass through the membrane via active transport. This is because the cellular membrane is mostly nonpolar, and polar and nonpolar molecules repel each other. Only nonpolar molecule (i.e. hormones) can pass through the membrane without active transportation.
