Phospholipids are the major lipid found in the cell membrane.
It is called that because the membrane is rather loose and moves easily since is a lipid. It is stabilized somewhat by cholesterol molecules (in animals cells only). The mosaic just means that there is more than one thing that makes up the membrane. Besides the cholesterol molecules there are various proteins embedded in the membrane as well.
Each cell in the body, depending on its function will have a different type of cell membrane lipid. The most common type of cell membrane is a phospholipid. phospholipids are composed of a glycerol head (polar) which is oriented towards the cytosol and 2 fatty acid tails (non polar) which are oriented together.
membrane lipid which is made up of phospholipids and glycolipids. both phospholipids and glycolipids makes up glycerolipid.
Makes the membrane less fluid by restraining the movements of phospholipids, but also lowers the temperature required for the membrane to solidify.
Oxygen and water molecules can penetrate the cell membrane due to small gaps that are created by the lipid molecules. Lipid molecules overlap each other which makes the gaps. The oxygen and water molecules then enter in the gaps. The cell membrane in this case is semi permeable.

A phospholipid bilayer makes up most of the cell membrane

The lipid bilayer makes up the membrane of a cell. The lipid bilayer consists of opposing phospholipids, where the polar ends of both the top layer and the bottom layer of phospholipids face opposite directions.
Phospholipids permit lipid-soluble materials to easily enter or leave the cell by diffusion through the cell membrane. Phospholipids form a bilayer or double layer which makes up most of the membrane.
I assume that by "Cell Membrane," you mean a lipid bi-layer that makes the cell membrane of micro-organisms. If that is what you mean, the iPhone does not have a cell membrane. There are not any lipid bi-layers anywhere in or around the iPhone.
While water does pass through the membrane if it has enough momentum, the apolar part of the lipid bilayer generally is what makes the membrane more or less waterproof.
this is the cell membrane made primarily of lipid molecules with proteins incorporated into it that aid in transport of molecules across the membrane
The cell membrane makes the boundary of the cell. It is a lipid bilayer.
