CYTOSKELETON
CYTOSKELETON
Located in cytosol of the cytoplasm
STRUCTURE                      FUNCTION
                                Gives shape to the
   Network of thin tubes        cell(like the inside of a
    and filaments (Made of       tent)
    Protein) that
                                Plays important roles in
    crisscrosses the cytosol
                                 intracellular transport
   Made up of
    Microfilaments,              Act as internal tracks
    Microtubules and             (for example:the
    Intermediate Filaments       movement of vesicles
                                 and organelles)
                                Cellular division.
MICROTUBULES
STRUCTURE                     FUNCTION
 Hollow tubes made of         Chromosome
  coiled tubulin (a type of     Movement(Cell Division)
  protein)                     Hold organelles in place
 Two subunits:                 and assists in organelle
 Alpha and Beta Tubulin        movement
 Radiate outward from         Cell Motility – Make up

  the centrosome near           Cilia and Flagella
  the nucleus                  Maintains cell’s shape
Microtubules
Microfilaments
Structure             Function
 Two strands of       Maintains cell’s
  intertwined actin     shape and movement
  protein               of cytoplasm
 Looks like a rope    Cell Motility (ex:
                        White blood Cells)
                       Cell Division

                      **Muscle cell
                        Contraction
MICROFILAMENTS
Intermediate Filaments
Structure                 Function
 Protein fibers coiled    Rods that anchor
  into cables               nucleus and other
                            organelles in their
                            place
                           Maintains cell shape
                            and Nucleus Shape
Intermediate Filaments
CENTROSOMES & CENTRIOLES
Centrioles and Centrosomes

Centrosome Structure        Centrioles Structure
 Contain two centrioles     Two short cylinders of
                              microtubules


Centrosome Function         Centrioles Function
 Microtubule Organizing     Act as anchors that

  Center                      microtubules attach to
 Contains two centrioles
                              during cell division to
  in the animal cell          move chromosomes.
CILIA AND FLAGELLA
CILIA AND FLAGELLA
Structure:              Function
Flagella- Made of        Movement of the
  microtubules. One       cell
  or two long strand
  that extends from        Aids in movement
  the cell Membrane         of fluids across the
Cilia- Many short           cell membrane
  hairlike structures
  that extend from
  the cell membrane
