No. Some secrete a covering.
The outermost living part of a cell is the cell membrane. The cell membrane regulates what comes into the cell and what goes out of the cell. It is composed of a double layer of phospholipids and proteins.
membrane or plasma membrane.
Both eukaryotic cells and prokaryotic cells have a plasma membrane.
the phospholipids. by weight it is half protein and half lipid
Yes, both plant and animal cells have a plasma membrane. The plasma membrane is a semi-permeable barrier that surrounds the cell and controls the movement of substances in and out of the cell.

That is the structure of plasma membrane adjectent or near the secondary cell wall in a cells. It's a living outermost boundary of all the cells.

ALL CELLS HAVE a plasma membrane
Some cells have glycocalyces and this then would be the outermost part of the cell for them but all cells must have a plasma membrane and therefore I think this would be the best answer to the question.
Plasma membrane is the cell component that forms pinocytic vesicles through the process of endocytosis. Pinocytic vesicles are small membrane-bound vesicles formed by invagination of the plasma membrane to bring in extracellular fluids.
Both eukaryotic cells and prokaryotic cells have a plasma membrane.
The plasma membrane of cells is found in both prokaryotic and eukaryotic cells.
Plasma membrane is the same as "cell membrane" it's one of the four characteristics of all cells. So plasma membrane is found "coating" the outside of all cells.
Phospholipid bi layer mainly.Otherthan proteins,carbohydrates,lipids canbe found
