Monotrichous (Mono means one): Single polar flagellum e.g. Vibrio cholerae, Campylobacter spp. (polar flagella often in pairs to give a “seagull” appearance).
Which of the following flagellation type in bacteria is polar?
What are polar flagella?
Polar flagella of Vibrio species can rotate at speeds as high as 100,000 rpm and effectively propel the bacteria in liquid as fast as 60 μm/s. … In addition to its propulsive role, the single polar flagellum of V. parahaemolyticus is believed to act as a tactile sensor controlling surface-induced gene expression.
What are different types of bacteria on the basis of flagellation?
Types and Examples of Flagella
- Monotrichous. – Single polar flagellum. – Example: Vibrio cholerae.
- Amphitrichous. – Single flagellum on both sides. – Example: Alkaligens faecalis.
- Lophotrichous. – Tufts of flagella at one or both sides. – Example: Spirillum.
- Peritrichous. – Numerous falgella all over the bacterial body.

Which of the following is non polar flagellation in bacteria?
The flagella are distributed over the surface of the bacterial cell in a characteristic manner. … They may be restricted to one or both the ends of the bacterium cell (polar flagellation) or may be distributed uniformly all over the body surface (non-polar flagellation). so your answer is peritrichous.
Which of the following bacteria has single polar flagellum?
Pseudomonas aeruginosa [15] and Vibrio cholerae [16] have a single polar flagellum at the cell pole.
Are all flagella polar?
Flagella may be variously distributed over the surface of bacterial cells in distinguishing patterns, but basically flagella are either polar (one or more flagella arising from one or both poles of the cell) or peritrichous (lateral flagella distributed over the entire cell surface).
What is a cluster of polar flagella called?
A cluster of polar flagella is called lophotrichous, therefore the answer is A. Amphitrichous refers to one or more flagella at each end of the…
What is an example of Lophotrichous?
Lophotrichous arrangement of flagella is the presence of multiple flagella at the same point in the cell. Most of the time, these flagella occur at the polar end of the cell. … Examples of a lophotrichous arrangement of flagella include Spirillium, Pseudomonas fluorescens, etc.
What are the 3 main types of bacteria?
Bacteria Shapes Bacteria can be assigned to three major groups based on shape. These include bacteria that are spherical (cocci), rod-shaped (bacilli) and spirals and others.
