13) What is the purpose of a bacterium's cell wall?
A) It provides direct protection from antibiotics.
B) It prevents sunlight from destroying the cell's DNA.
C) It prevents water from diffusing into the cell.
D) Bacteria do not have a cell wall.
The bacterial cell wall is made up of a complex and mesh-like structure that is essential for maintaining the integrity of shape and structure. It contains peptidoglycan which is an important protective bacteria for the cells. Both the gram-positive and negative bacterial cells of the cytoplasmic membrane are encapsulated by peptidoglycan. Peptidoglycan is a highly, rigid, complex, and conserved structure of amino acids and polymeric carbohydrates.
