Parts used for Cell Structure and Cell Division (Page 84)

2. CYTOSKELETON

3. 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.

4. 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

5. Microtubules

6. 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

7. MICROFILAMENTS

8. 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

9. Intermediate Filaments

10. CENTROSOMES & CENTRIOLES

11. 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.

12. CILIA AND FLAGELLA

13. 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
