There are many examples of types of lipids in a Cell membrane; one is phospolipids.
phospholipids
Some of the proteins and lipids do control movement of materials into and out of the cell.
cell membrane
Three different types of molecules appear in the membrane of a cell. These molecules are lipids, proteins, and carbohydrates.
The cell membrane is made mostly of lipids (fats) and they have some proteins in them; somewhat like islands in a sea.
Lipids or oil get through plasma membrane because plasma membrane is a selectively permeable membrane. It allows entry and exit of only some substances through it.
Membrane bio- genesis is the process, when some proteins and lipids (produced in SER)help in building the cell membrane, inside a cell.

Some plant cells have a cell membrane, as well as a cell wall.
The GA in lipids lends some rigidity to the cell membrane. It helps with shape and aids in structure.
IT depends on what cell. In the plant cell it is the cell wall and the cell membrane. But in the animal cell it is only the cell membrane.

That is just another name for the cell membrane. It's main job is to keep the things that are on the inside of a cell inside, and keep what things are outside the cell on the outside. It is also called a semipermeable membrane because it can allow some things, under certain situations, to cross the phospholipid bilayer to enter or exit the cell.The phsopholipid bilayer is the thin polar cell membrane comprised of two layers of lipids. This membrane surrounds a cell to keep substances (ions, proteins, etc) in or out of the cell, but also allow selected substances to pass through the cell membrane as required.
The lipids molecules that form the membrane are fluid. They can move about relative to one another in a fluid manner. Some of the proteins are also free to move about sothat the mosiac or pattern of lipids and proteins changes. Because of these characteristics scientists call their model of the dynamic cell membrane the fluid the fluid mosiac model.
