Sagot :
Cell membrane is composed of two layers of fatty acids these fatty acids have two domains hydrophobic and hydrophilic.
The plasma membrane is also referred to as the cell membrane, which is made up of carrier proteins, lipid molecules, and hydrocarbon chains.
The two layers that selectively allow the material to pass through the cell membrane are hydrophilic and hydrophobic ends of phospholipids.
The lipid bilayer function can be explained as:
- The lipid bilayer has hydrophobic and hydrophilic ends, which selectively allows ions, molecules, and other substances to pass through them.
- Lipid bilayers keep out the toxic substances and protect the cell from the surrounding.
Thus, the two layers of the plasma membrane are made up of phospholipids having hydrophilic and hydrophobic ends.
