Detailed explanation-1: -Pili can act as receptors for bacteriophage, facilitate DNA uptake and transfer (conjugation), and, in at least type IV pili, function in cellular motility. The primary function of most pili, however, is to act as scaffolding for the presentation of specific adhesive moieties.
Detailed explanation-2: -Pili allow cells to “crawl” across a surface. Pili are short filaments on the surface of archaea cells that allow neighboring cells to adhere to one another. Pili allow cells to share genetic information through a process called DNA transfer or conjugation.
Detailed explanation-3: -Pili are short, hair-like structures on the cell surface of prokaryotic cells. They can have a role in movement, but are more often involved in adherence to surfaces, which facilitates infection, and is a key virulence characteristic.
Detailed explanation-4: -The short attachment pili or fimbriae are organelles of adhesion allowing bacteria to colonize environmental surfaces or cells and resist flushing. The pilus has a shaft composed of a protein called pilin.
Detailed explanation-5: -Flagella and pili are both necessary for efficient attachment of Methanococcus maripaludis to surfaces.
