Polar flagella are longer than their peritrichous counterparts. 36 nm which extended ca. Biology questions and answers.

Bacterial flagella are hollow helical tubes with a length of several μms and a diameter of about 24 nm Figure 7. The mechanical effect of this flagellar movement is to rotate the cell body in a direction opposite to that of the flagella. Spirillum volutans have flagella which are lophotrichous in nature ie.
