WebJul 14, 2024 · 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. Why is the flagella important to the cell? A flagellate can have one or several flagella.
