Answer:</h2><h2>when the membranes are fused, the polar parts of the phospholipids from one cell will interact with the phospholipids from the other cell .</h2>
Explanation:
Cell membrane is composed of phospholipid bilayer . Cell membrane is hydrophilic at the surface of outside of the cell and inside surface of the cell thus both surface of cell membrane is a hydrophilic . Interiorly cell membrane is hydrophobic or nonpolar region because membrane composed of long fatty acid chain interiorly . Inner surface of cell membrane have no contact with water or polar molecules . When membrane binds to each other then the polar parts of the phospholipids from one cell will interact with the phospholipids from the other cell , while nonpolar parts of cell avoid water and create bilayer phospholipid where hydrophobic tails are in between the hydrophilic heads .
