Cytoskeleton

Question 1

What are the 4 things the cytoskeleton aids?

Answer 1

Cell shape
Cell movement
Organelle movement
Cell division

Question 2

Cell shape

Answer 2

For cells without cell walls, the cytoskeleton determines the shape of the cell. Intermediate filaments are responsible for this.

Question 3

Cell movement

Answer 3

Microfilaments and microtubules are always assembling and disassembling which results in forces that move the cell.

Question 4

Cell division

Answer 4

Microtubules accomplish the separation of the chromosomes.

A ring of microfilaments in animal cells constrict central region of cell to help divide the two developing cells.

Question 5

Organelle movement

Answer 5

Microtubules and microfilaments move the organelles. For example, they move vesicles into the cell after it has engulfed a particle outside the cell.

Question 6

Describe the structure of the cytoskeleton

Answer 6

A series of protein threads made up of microfilaments, microtubules and intermediate fibres.
