According to the research, the correct answer is fiber composites. Because cell walls consist of a cross-linked network of long filaments embedded in a stiff surrounding material, they can be called fiber composites.
<h3>What are 
cell walls?</h3>
It is a network that covers prokaryotic cells and plant cells that is located outside the plasma membrane, helping to form the structure.
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.
