Answer:

False

Explanation:

The glycocalyx is the layer surrounding the plasma membrane of the eukaryotic and prokaryotic cells.

The glycocalyx is composed of the carbohydrates and the protein molecules like the proteoglycans, glycosaminoglycans and the other glycoproteins.

The glycocalyx has been identified in the bacterial cells as a protective layer from the host bu in eukaryotes the glycocalyx helps in the cell to cell interaction and communication.

Since the glycocalyx is not composed primarily of the proteins but of the carbohydrates and the proteins therefore false is the correct answer.

Answer: False. It is not glycocalyx.

Explanation:

Glycocalyx is a carbohydrate enriched membrane bound layer that surrounds the cell plasma of eukaryotic cells and prokaryotic cells, especially bacteria. It act as a barrier between the cells and its environments. In bacterial cell, it act as protective coat from host factors.

Glycocalyx help in cell to cell interaction or communication in eukaryotic cell. It is involved in diseases development and progression.
