cytoskeleton

• cytoskeleton 


  a network of protein threads running through the cytoplasm
• how are protein threads arranged in eukaryotic cells

  as microfilaments and microtubules
• microfilaments 


  very thin protein strands
• microtubules 


  tiny protein cylinders
• functions of the cytoskeleton:

  1. The microtubules and microfilaments support the cell's organelles, keeping them in position.
  2. help to strengthen the cell and maintain its shape.
  3. they're responsible for the transport of organelles and materials within the cell.
  4. The proteins of the cytoskeleton can cause the cell to move.
• The cytoskeleton is dynamic (constantly changing), which allows it to respond to changes in the cell and carry out its functions.
