Bacteria That Have a Single Polar Flagellum at One End

Question

Bacteria that have a single polar flagellum at one end are referred to as
A)amphitrichous.
B)monotrichous.
C)peritrichous.
D)lophotrichous.

Accepted Answer

Bacteria with a single flagellum at one end are called monotrichous. "Mono" means one or single, and "trichous" refers to the number and location of the flagella. Amphitrichous bacteria have a flagellum at each end, peritrichous bacteria have multiple flagella distributed across the surface of the cell, and lophotrichous bacteria have multiple flagella clustered at one or both ends of the cell.
