Carbohydrate layer on the plasma membrane includes all of the following except:
(a) adhesion
(b) recognition
(c) gives a cell its distinctive characteristics
(d) none of these answers are correct

c) Gives a cell its distinctive characteristics

Explanation:

Carbohydrates perform two main functions in the cell's membrane: they participate in cell recognition and adhesion (cell-cell signaling or cell-pathogen interactions), they also have a structural role as a physical barrier.

Most of the carbohydrates linked to the membrane are in the form of glycoproteins oy glycolipids, these are the molecules that share information and recognize host cells. Glycocalyx is another way we find carbohydrates in the cell membrane, this layer has cell-adhesion molecules that enable cells to adhere to each other.
