Cytoskeleton

• What is the cytoskeleton composed of?

  Complex structure of tubules and fibers
• What is the primary function of the cytoskeleton?

  Provides structure and shape to the cell
• What does the cytoskeleton contain?

  A complex network of proteins
• How does the cytoskeleton change cell shape?

  By rearranging its tubules and fibers
• What role does the cytoskeleton play in moving materials within the cell?

  Acts as tracks for the transport of molecules
• What are microtubules made of?

  Protein units called tubulin
• What is the structure of microtubules?

  They are tubular in shape
• What is the function of microtubules?

  Form spindle fibers that split chromosomes
• What is the role of microfilaments in the cytoskeleton?

  Cell movement and contraction during cytokinesis
• What are microfilaments made of?

  Protein units called actin
• What is the structure of intermediate fibers?

  They are fibrous in structure
• What is the function of intermediate fibers?

  Provide mechanical strength to cells
• What are the three main components of the cytoskeleton?

  Microtubules, microfilaments, intermediate fibers
• How do microtubules and microfilaments differ in function?

  Microtubules form spindle fibers; microfilaments aid movement
• What is the relationship between the cytoskeleton and cell shape?

  The cytoskeleton provides structure and maintains shape
