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.
The Cell Membrane, or the Cell Wall would be the outermost limit depending on the type of cell. Some cells also have cilia or flagella.
The Cell Membrane
the cell membrane
It is called the cell wall.
The outer layer of a cell is the cell membrane or plasma membrane
The outermost border in a bacteria cell is called membrane. This is also commonly referred to as the cell wall.
the cell membrane. It is a protein mosaic this is hydrophobic on both sides and hydrophllic in the center.
a cell This could be a cell, but it could also be a specimen. The question is not sufficiently definite.
no there is not a limit to how small a living cell could be
It is called the cell wall.
The outer boundary of a cell is called the cell membrane, and is composed of a phospholipid bilayer.
the cell membrane
The outer boundary of a plant cell is the cell wall.
The outer edge of a plant cell is called the cell wall
both as the are the outer wall of a cell in any living thing
The cell membrane.
Cell Membrane
the cell membrane is the outer living cell covering the cell wall is over the cellmembrane
I'm not sure if this answers your question, but the LAYER of this outer skin, is called the Epidermis, and the inside, the Dermis.
