Question

Select the wrong statement

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

Answer 1

The correct option is D Pili and fimbriae are mainly involved in motility of bacterial cells.

Flagella are the prokaryotic structures that are usually involved in locomotion. Pili and Fimbriae are involved in the attachment of the cell to specific surfaces and also in the process of conjugation (transfer of bacterial plasmid).
All the other statements are true.
