Researchers have found that mixtures of phospholipids placed in water or salt solutions tend to spontaneously form small spherical units that resemble living cells.

Explanation:

Phospholipids are the major component that forms the cell membranes. They contain the molecules with hydrophilic phosphate. So, when these phospholipids are dissolved in the water they form a new structure like the spherical shape units. Even with the salt solution mixture the phospholipids instantly turns into the unit that is similar to the living cells. The phospholipids also have the 'non-polar and polar components' to associate with water.
