There is a water-loving side outside the cell.
Explanation:
The lipid bilayer is formed in such the simplest way that the hydrophobic facet is on within| and therefore the water affectioned (hydrophilic) facet is on the surface and inside.
It is a two-layered arrangement of phosphate and macromolecule molecules that is kind of cytomembrane, the hydrophobic macromolecule ends facing inward and therefore the hydrophilic phosphate ends facing outward.
