CYTOSKELETON

Page 3: CELL PARTS Parts used for Cell Structure and Cell Division (Page 84)

CYTOSKELETONLocated 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.

Page 4: CELL PARTS Parts used for Cell Structure and Cell Division (Page 84)

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

Page 6: CELL PARTS Parts used for Cell Structure and Cell Division (Page 84)

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

Page 8: CELL PARTS Parts used for Cell Structure and Cell Division (Page 84)

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

Page 11: CELL PARTS Parts used for Cell Structure and Cell Division (Page 84)

Centrioles and Centrosomes

Centrosome Structure Contain two centrioles

Centrosome Function Microtubule

Organizing Center Contains two

centrioles in the animal cell

Centrioles Structure Two short cylinders of

microtubules

Centrioles Function Act as anchors that

microtubules attach to during cell division to move chromosomes.

CILIA AND FLAGELLA

Page 13: CELL PARTS Parts used for Cell Structure and Cell Division (Page 84)

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
