CELL PARTS
Parts used for Cell Structure and Cell
Division (Page 84)
CYTOSKELETON
CYTOSKELETON
Located in cytosol of the cytoplasm
STRUCTURE


Network of thin tubes
and filaments (Made of
Protein) that
crisscrosses the cytosol
Made up of
Microfilaments,
Microtubules and
Intermediate Filaments
FUNCTION
 Gives shape to the
cell(like the inside of a
tent)
 Plays important roles in
intracellular transport
Act as internal tracks
(for example:the
movement of vesicles
and organelles)
 Cellular division.
MICROTUBULES
STRUCTURE
 Hollow tubes made of
coiled tubulin (a type of
protein)
 Two subunits:
 Alpha and Beta Tubulin
 Radiate outward from
the centrosome near
the nucleus
FUNCTION
 Chromosome
Movement(Cell Division)
 Hold organelles in place
and assists in organelle
movement
 Cell Motility – Make up
Cilia and Flagella
 Maintains cell’s shape
Microtubules
Microfilaments
Structure
 Two strands of
intertwined actin
protein
 Looks like a rope
Function
 Maintains cell’s
shape and movement
of cytoplasm
 Cell Motility (ex:
White blood Cells)
 Cell Division
**Muscle cell
Contraction
MICROFILAMENTS
Intermediate Filaments
Structure
 Protein fibers coiled
into cables
Function
 Rods that anchor
nucleus and other
organelles in their
place
 Maintains cell shape
and Nucleus Shape
Intermediate Filaments
CENTROSOMES & CENTRIOLES
Centrioles and Centrosomes
Centrosome Structure
 Contain two centrioles
Centrioles Structure
 Two short cylinders of
microtubules
Centrosome Function
 Microtubule Organizing
Center
 Contains two centrioles
in the animal cell
Centrioles Function
 Act as anchors that
microtubules attach to
during cell division to
move chromosomes.
CILIA AND FLAGELLA
CILIA AND FLAGELLA
Structure:
Flagella- Made of
microtubules. One
or two long strand
that extends from
the cell Membrane
Cilia- Many short
hairlike structures
that extend from
the cell membrane
Function
 Movement of the
cell

Aids in movement
of fluids across the
cell membrane
