The entire cell wall of bacteria is often regarded as a single huge molecule or molecular complex called_:

Explanation

The sacculus is the rigid layer that forms the outermost part of the cell wall in bacteria. It is made up of peptidoglycan, a polymer of sugars and amino acids. The sacculus is responsible for providing the cell with its shape and strength. It also helps to protect the cell from the environment and from attack by the host immune system. Hence the entire cell wall of bacteria is often regarded as a single huge molecule or molecular complex called sacculus.
