Question

which of the following biomolecules are the primary component of cell wall?
○ carbohydrates
○ lipids
○ proteins
○ nucleic acids

Explanation:

In plant cells, the cell wall is primarily composed of cellulose, which is a carbohydrate (a polysaccharide). Fungal cell walls have chitin (also a carbohydrate), and bacterial cell walls have peptidoglycan (with carbohydrate components). Lipids are main in cell membranes, proteins have various functional roles, and nucleic acids are for genetic info, so carbohydrates are the primary biomolecule for cell walls.

Answer:

A. Carbohydrates
