For most cells, it is the cell membrane.
Cells have a plasma membrane that is very selectively permeable i.e, will allow entry of substances that are necessary for the cell functioning.
In case of an egg cell, it is surrounded by follicular cells. It provides protection from various acidic conditions.
For a plant cell, the cell wall serves as a barrier.

What are Cells that let some substances in keep others out let some substances out?
The cell membrane controls what comes in and out of cells.
What structure forms a protective layer rich in glycoproteins on the surface of cells?
Matrix
What performs the same function as the cell wall?
A door is an example of a cell wall. It is a protective wall, provides, and maintains the shape of these cells. They also serve as a protective barrier.
The testicular cells that construct the blood- testis barrier are the?
Sertoli cells, a kind of sustentacular cells.
Do tiny cells have a protective coating?
yes
All cells have a protective barrier that is formed of proteins and a lipid bilayer. What is the name of this barrier?
cell membrane
What protective barrier separates cells contents from the cells environment?
A cell membrane, or cell wall.
Are bacterial Cells prokaryotic Cells?
The answer is yes. They possess no nucleus and they they have an exterior protective Cell barrier.
Who protective layer that covers a cells surface?
Either the cell membrane, or the cell wall. The cell membrane is most common in animals, and protists, whereas some monerans, and most plants and fungi have a cell wall.
Provides and maintains the shape of cells and serves as a protective barrier?
receives materials from the endoplasmic reticulum and send them to other parts of the cells.
What type of epithelium covers the body and serves as protection for the body surface?
The type of epithelium that covers the body and provides protection for the body surface is stratified squamous epithelium. It is composed of multiple layers of flat cells that are tightly packed together, forming a barrier against mechanical damage, pathogens, and dehydration.

Matrix
What are perineural cells?
Perineural cells are formed from the perineurium, which is the middle layer of the protective perineural sheath. These cells isolate bundles of axons from connective tissues and form a diffusion barrier
