A cell coat is a covering over the plasma membrane of most animal cells. It consists of glycoprotiens and polysaccharides and has a chemical composition that differs from comparable structures in either plants or bacteria. The cell coat provides a biochemical identity at the surface of the cells and these forms of cellular identity are under genetic control. AB and MN antigens are on the surface of red blood cells and histocompatability antigens, which elicit an immune response during tissue and organ transplants, are present in other cells. These are recognition sites that transfer specific chemical signals across the cell membrane into the cell.
The cell coat, or glycocalyx, is a layer of carbohydrates attached to proteins and lipids on the outer surface of cell membranes. It plays a role in cell recognition, immunity, and protection. The composition of the cell coat can vary between cell types and is important for cell-cell interactions.

What is the name for a package of nucleic acid wrapped in a protein coat that must use a host cell's machinery to reproduce itself?
A virus is a package of nucleic acid wrapped in a protein coat that requires a host cell's machinery to replicate.
What is the sugar coat on the cell surface?
The sugar coat on the cell surface is a layer of carbohydrates called glycocalyx. This structure helps cells adhere to one another, plays a role in cell signaling and recognition, and provides protection against pathogens. The composition of the sugar coat can vary between cell types and can influence the cell's function and interactions with its environment.
Vesicles are formed by an action of the?
Vesicles are formed by the action of proteins called coat proteins (such as clathrin or COPII) that help shape the membrane into a vesicle. These coat proteins gather at a specific site on the membrane and facilitate the pinching off of the vesicle to transport molecules within the cell.
Is a virus made of more than one cell?
No, a virus is not made up of cells. Instead, it is composed of genetic material (either DNA or RNA) encapsulated in a protein coat. Viruses can only replicate by infecting host cells and using the host cell's machinery to produce more viruses.
Does a virus contain a cell membrane?
No, viruses do not contain a cell membrane. Viruses are simple infectious agents composed of genetic material (DNA or RNA) surrounded by a protein coat called a capsid. They lack the complex cellular structures found in living cells.
What type of living things has a nucleus a bridge coat of cellulose and chloroplast?
Bridge coat of cellose is cell wall.So the cell is a plant cell.
What is the jellly coat of a egg cell called?
The jelly coat makes sure that only one sperm cell can enter the egg cell.
Does an animal cell have a cell coat?
yes, of course
Where is the cell membrane located in the Cell?
It is internal to the prokaryotic Cell wall as well as the eukaryotic Cell coat.
Cell membrane and protein coat same thing?
No, the cell membrane and protein coat are not the same thing. The cell membrane is a phospholipid bilayer that surrounds the cell, providing structure and regulating what goes in and out. A protein coat, on the other hand, is a protective layer made of proteins that surrounds some viruses.
What is a cell with a hard coat protected around it?
spore
What does the protein coat do during a virus invation?
Generally, excepting a retrovirus like HIV, the coat stay out side of the victim cell while the genetic material is injected into the cell.
Where cell coat is found?
It's actually called a cell wall, and it is found outside the plasma membrane which surrounds the cell.
What are two functions of a virues protein coat?
The two functions of a virus's protein coat are to protect the genetic material inside and to react with the cell wall of a potential host cell, thus causing the genetic material to be injected into the host cell.
What are two function's of a virus's protein coat?
The two functions of a virus's protein coat are to protect the genetic material inside and to react with the cell wall of a potential host cell, thus causing the genetic material to be injected into the host cell.
Are bacteria and viruses surrounded by a protein coat?
Viruses are surrounded by a protein coat called a capsid, which protects their genetic material. Some bacteria have an outer protein coat called a capsule, which provides protection and helps them adhere to surfaces.
Surrounding each Cell in your body is a what and a what?
That is a bi-lipid Cell plasma membrane coated with a glyco-callyx Cell coat. Plant Cell plasma membranes are coated with a cellulosic Cell wall.
