Phospholipids have phosphate group heads that are hydrophilic while the fatty acid tails are hydrophobic.
They are able to form cell membrane as they automatically arrange themselves in the required pattern in water because of these properties.To form membranes, these line up next to each other with their heads on the outside of the cell and their tails on the inside. A second layer of phospholipids also forms with heads on the inside of the cell and tails facing away.
In this way a double layer is formed with phosphate group heads on the outside, and fatty acid tails on the inside. This double layer, called a lipid bi-layer, forms the main part of the cell membrane.
