CYTOSKELETON
Those little hairlike strands on
the outside of
the animal cell
are the CILIA

 The
FLAGELLA
is what
looks like a
tail on the
cell
Function & Importance
Cytoskeleton
Flagella
Cilia
•Maintains cell
shape
•Protects Cell
•Enables cellular
motion
•Plays an
important role in
intracellular
transport
•Is very
important in cell
division
•Helps with
movement
(example: sperm)
•Helps with
movement
outside cell
(example:
Sweeping dust
particles)
Plant or Animal???

Filaments
Structure of a Cytoskeleton, Flagella and Cilia
A cytoskeleton is made up
of microtubules,
microfilaments and
intermediate filaments. It
also contains a plasma
membrane.
The flagella and Cilia are also
made up of plasma membranes
and microtubules. Unlike
Cytoskeleton they contain Dynein
Arms and Radial spokes.
