Question 10

Draw and state the function of the cytoskeleton

Answer 10

Structural network of fibres required for cell support, maintaining cellular shape and enable cellular movement

Question 11

What are the different categories of the cytoskeleton, and what are their roles?

Answer 11

Microfilaments: made of actin protein, involved in intracellular movement and muscle contraption
Intermediate Filaments: strong fibrous proteins, strengthens cell
Microtubules: made of tubule proteins, involved in cell movement, spindle fibres
