The cell wall in bacteria is primarily composed of which of the following substances?
A
Peptidoglycan
B
Cellulose
C
Lignin
D
Chitin
Verified step by step guidance1
Understand that the bacterial cell wall provides structural support and protection to the cell.
Recall that the primary component of the bacterial cell wall is a unique polymer that differs from those found in plants and fungi.
Identify that cellulose is a polysaccharide found mainly in plant cell walls, not bacteria.
Recognize that lignin is a complex polymer found in the cell walls of plants, providing rigidity, but it is not present in bacteria.
Know that chitin is a polysaccharide found in fungal cell walls and the exoskeletons of arthropods, not in bacteria; therefore, the bacterial cell wall is primarily composed of peptidoglycan.
