The hydrophobic tails aggregate to form a bi layer.
Explanation:
Phospholipids are major constituents of the plasma membrane. These are triglycerides having lipid part and phosphate part. The phosphate portion is the water-loving/hydrophilic and the glycerol tail or lipid part is water hating/hydrophobic. Hence, it is an amphipathic molecule. The hydrophobic tail aggregate with each other to form a lipid bilayer in the water. Therefore, the lipid tails prevent water molecules to enter the bilayer.
