What are the functions of bacterial cell walls?

Posted March 1, 2023


The bacterial cell wall performs several crucial functions.

  • Helps to maintain cell shape and structural integrity, thereby helping the cell move, grow, reproduce, and obtain nutrients
  • Provides overall strength to the cell
  • Protects the cell from osmotic lysis as it moves around different environments
  • Prevents toxic substances from entering the cell
  • Contributes to the pathogenicity or disease-causing ability of the bacteria
