Free balling it here but I think the answer is PROTEINS
A carbohydrate is used to help mark cells. This carbohydrate sequence is unique for those cells.
Cells recognize each other through glycoproteins. This is important because cells need to recognize each other in order to function correctly and control the health of your body.
This is protein called a self-marker. It sort of tells the immune cells that it belongs. If the immune cell doesn't read it right, it will attack and cause an autoimmune problem.
The chain is attached with a marker protein, and together the chain and marker protein help identify the cell to other nearby cells.

antigens
Stop dividing.
To attract other cells that specialize in disposing of cellular corpses.
Some white cells call macrophages will eat germs. Some others will tag germs with a marker that tells the other cells that they need to get rid of them.
Not in language. Cells communicate with other cells on a rudimentary basis by releasing various chemicals that reflect their condition and functioning. Nerve cells can directly signal other nerve cells, and the sensory or muscle cells they are linked to.

Cell recognition proteins allow cells to recognize each other as well as other molecules.
