A flagellum (plural: flagella) is a long, slender projection from the cell body, whose function is to propel a unicellular or small multicellular organism. The depicted type of flagellum is found in bacteria such as E. coli and Salmonella , and rotates like a propeller when the bacterium swims.
A flagellum (/ f l ə ˈ dʒ ɛ l əm /; pl.: flagella) (Latin for 'whip' or 'scourge') is a hair-like appendage that protrudes from certain plant and animal sperm cells, from fungal spores (), and from a wide range of microorganisms to provide motility.
A flagellate is a cell or organism with one or more whip-like appendages called flagella. The word flagellate also describes a particular construction (or level of organization) characteristic of many prokaryotes and eukaryotes and their means of motion. The term presently does not imply any specific relationship or classification of the ...
The 16-cell Gonium colony shown in the diagram on the right is organized into two concentric squares of respectively 4 and 12 cells, each biflagellated, held together by an extracellular matrix. [51] All flagella point out on the same side: It exhibits a much lower symmetry than Volvox, lacking anterior-posterior symmetry.
English: The Colonial Flagellate Hypothesis proposes that multicellular organisms evolved from a single flagellated cell. it is believed that a group of these unicellular flagellates combine to form an aggregate then form a sphere which develops specialized cells (such as reproductive cells), and then fold in on themselves to create a tissue layer.
Lophotrichous – A tuft of flagella found at one of the cell poles; Amphitrichous – Single flagellum found at each of two opposite poles; Peritrichous – Multiple flagella found at several locations about the cell; The bacterial flagellum consists of three basic components: a whip-like filament, a motor complex, and a hook that connects them.

A key feature of the genus is its two anterior flagella, each as long as the other. [8] The flagellar microtubules may each be disassembled by the cell to provide spare material to rebuild the other's microtubules if they are damaged. [11] Cell wall is made up of a glycoprotein and non-cellulosic polysaccharides instead of cellulose.
