3. The lipid bilayer of the plasma membrane is composed of what?
Your Answer:
Phospholipid.
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.
