Bacterial flagella: types and structure

by

Introduction Strains of bacteria which are motile possess filamentous, cytoplasmic appendages protruding through cell wall called flagella. This effect screw like propulsive movements and act as organs of locomotion. They are much thinner than the flagella or cilia of eukaryotes. The flagellum is a long, thin filament, hair-like, un-branched, twisted spirally in an open, regular … Read more
