Yes, how else could the cell live. Cell membranes have structures (holes) in them to allow things to move in and out. These holes are special structures in the membrane and they "control" what goes across the membrane. I have made a link below to a diagram of the cell membrane to show some of these structures.
The cell membrane is made of carbohydrate, lipid, and protein molecules.
The cell membrane is made of the lipid bilayer which contains lipids and proteins.
this is the cell membrane made primarily of lipid molecules with proteins incorporated into it that aid in transport of molecules across the membrane

cell membrane
Cell membrane pores are made up of protein.
The cell membrane is made of carbohydrate, lipid, and protein molecules.
The cell membrane is made up of a bilayer of phospholipids.
The cell membrane is made of the lipid bilayer which contains lipids and proteins.
The cell membrane is made up of phospholipids; hydrophobic and hydrophilic. The cell is only in plant cells and is made of cellulose.
