Answer 1

Often these molecules are carbohydrates, attached to certain lipids, or also I believe are called as glycolipids. These are marker molecules and are used to distinguish cells from each other. As cells can differentiate from one another based on the composition of the carbohydrates present on the lipids, I believe.

Answer 2

On the outer surface of the plasma membrane, there are CARBOHYDRATE CHAINS that identify the cell type.

Carbohydrates represent the third most important component of the plasma membrane.

These carbohydrates interact with proteins to form glycoproteins or interact with lipids to form glycolipids that are located on the surface of the cell membranes (including the plasma membrane)

In conclusion, on the outer surface of the plasma membrane, there are CARBOHYDRATE CHAINS that identify the cell type.
