In this sense, since it is made up of a network of carbohydrates, phospholipids and structural proteins, and the different cell types of plants can be identified by their characteristics, they can be called fiber composites.

Therefore, we can conclude that cell walls are a network embedded in a matrix composed of carbohydrates and proteins.
