Flagella are organs used to propel the cell in a liquid environment. According to the flagella distribution patterns, bacteria with a single flagellum at each pole are called _amphitrichous bacteria.

What is flagellum?

The Flagellum is an organ used by bacteria and some eukaryotic cells to propel in a liquid environment. It is a motility organ.

The number and size of flagella in a cell vary according to the species.

All of them have the same motion function.

What structures compose the flagellum?

Flagella are basically composed of three main parts,

  • the basal body
  • helical filament
  • the hook

Bacteria classification

According to the number and distribution pattern of flagella in the cell, bacteria can be  classified into the following groups,

  • monotrichous ⇒  1 flagellum
  • amphitrichous ⇒  1 flagellum at each extreme of the cell
  • lophotrichous  ⇒  severa flagella over the cell
  • peritrichous  ⇒  several flagella distributed over the cell excepting the poles.

Bacteria with a single flagellum at each pole are called _amphitrichous bacteria.
