A phosphate group and a lipid combine to from the phospholipid bilayer (cell membrane).
Phospholipids and Proteins
Proteins and lipids don't have cell membranes but are the molecules that make up the bulk of what a cell membrane is.
A double layer of phospholipids makes up most of your cell membranes

Osmosis is the water molecules diffusion across the cell membranes. More informations can be find at en.wikipedia.org/wiki/Diffusion
