Answer:
Glycocalyx
Explanation:
Most of the eukaryotic cells have a coating outside their cell membrane. This coating is called the glycocalyx. It consists of glycoproteins and glycolipids. The sugar parts of these compounds are in contact with the underlying plasma membrane. The function of the glycocalyx is to protect the cell. Certain specific molecules of the glycocalyx are involved in the recognition of cells so that they can recognize one another to make contact.
