Question:
Were is the location of a flagella in a cell?
Replies:
A flagellum (singular) is like a tail: it is a cell-organelle that is attached in the cell
membrane, facing outwards. In most flagellate bacteria and single-cellular eukaryotes, one or
more flagella are visible by microscopy as tail-like structures. In some bacteria (particular
spirochetes) flagella lay as a network between the inner and outer membrane, so that they are
not visible from the outside. They presumably keep the bacteria in their typical spiral shape.
In other bacteria a bunch of flagella are present at the
tip of the cell, like a witch broom. In others, only a single flagellum is present. But always
one end of the flagellum is attached to the membrane, through a motor which makes it rotate, and
the other end is free.
