Q23 / 180 · NEET 2016 (Phase 2) · Botany

Select the wrong statement.

  • A
    Bacterial cell wall is made up of peptidoglycan
  • Correct answer
    B
    Pili and fimbriae are mainly involved in motility of bacterial cells
  • C
    Cyanobacteria lack flagellated cells
  • D
    Mycoplasma is a wall - less microorganism

Solution

Pili and fimbriae are surface structures of 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.

Hence, the correct answer is option: 'B'.
