In bacteria, what role does the pili play?
The pili allows for mobility, sort of a "twitching" motion, in bacteria. It also functions in congugation to transmit genetic material.
Reply:Pili connect the bacterium to another of its species, or to another bacterium of a different species, and build a bridge between the cytoplasms of either cell. That enables the transfer of plasmids between the bacteria. An exchanged plasmid can add new functions to a bacterium, e.g., an antibiotic resistance.
