The lipid bilayer of the plasma membrane is composed of what? ✓The cell
membrane is a bilayer composed primarily of amphipathic phospholipids,
meaning they contain a polar hydrophilic (water loving) head group and a
non-polar hydrophobic (water fearing) tail region. The lipid bilayer is
situated in such a way where the non-polar tail groups face inward thus
orienting the polar head groups to interact with water both outside and
inside of the cell.
