Atrichous bacteria
Flagellatiion
Bacterial cell shows a prokaryotic structure 1:Flagellation The pattern of flagellar arrangement (flagellation) is a good identification mark in bacteria. Flagella are either confined to the pole or poles or it may be present alround the body of the bacterium. However, bacteria can be grouped as under on the basis of flagellation: Bacterial Flagellation A. Atrichous B.Monotrichous C. Flagellation D. Amphitrichous E.Lophotrichous F.Peritrichous Atrichous - Bacteria that lack flagella. Monotrichous - Single flagellum on either of the poles of the bacterial cell. Amphitrichous - One flagellum or more on each pole of the bacterial cell Lophotrichous - Flagella in groups present on one pole of the bacterium. Peritrichous - Flagella present allround the body of the bacterial cell 2:Cell wall : They are considered plants due to the presence of cell wall.It is about 100-250{Armstrongs}.it is made of peptidoglycogenalso known as murein or mucopeptide. The cell wall of gram positive bacteria is characterised by the presence of teconic acid .The cell wall is permeable to water and ions of small molecules
