Select the wrong statement
Options
- ABacteria cell wall is made up of peptidoglycan
- BPili and fimbriae are mainly involved in motility of bacterial cells
- CCyanobacteria lack flagellated cells
- DMycoplasma is a wall - less microorganism
Correct answer
B. Pili and fimbriae are mainly involved in motility of bacterial cells
Step-by-step solution
Pili and fimbriae are surface structures of the bacteria that do not play a role in motility. Pili and fimbriae are elongated, hollow appendages seen in Gram-negative bacteria made of a unique protein, pilin. They serve in the attachment of bacteria with substratum and not in movement.
