A bacterium does not continuously swim at one speed in one direction. Different arrangements and structures of flagella contribute to changes in speed and direction when necessary. How does motility relate to flagellation?.

Respuesta :

Different arrangements and structures of flagella contribute to changes in speed and direction when necessary. Motility relates to flagellation as:

  1. Polar flagella (in any one or both the poles of the bacterium) makes the organism move very quickly in a particular direction.
  2. Peritrichous flagella (present all over the cell) helps the organism in  rotation and tumbling.
  3. Amphitrichous flagella ( present in bulk at both the ends) move the organism slowly as these flagella work alternately and hence stop periodically to change directions).

Flagella is a hair like structure present in both prokaryotic as well as eukaryotic cell. It helps in motility. An organism can have a single flagella or multiple and these can be arranged in various ways.
