Cilia and flagella structures found in
prokaryotes as well some
eukaryotic cells. play defense,
nutrition movement roles for cell.
In eukaryotic of protists and
they originate from
that migrate towards plasma
membrane and into
structures projected the cell.
Each or flagellum is of nine
peripheral of microtubules and
central pair all by membrane.
(In , flagella are made a
protein named and there can
be fimbria made pilin.)

In the base ofeach cilium
flagellum in the membrane
there are that work as
motors providing movement
these structures with
spending. Due to energy spending
ciliated flagellated eukaryoticcells
have large number of .

In humans ciliated can be found,
example, in the and
tracheal epithelium. these tissues the
have the defensive of
sweeping mucous foreign
substances that the airways.
Sperm a typical example
flagellated cells, their is the
propulsion for the movement
