Presentation Transcript

  1. Cell Shape and Mobilitythe Cytoskeleton

  2. Cytoskeleton • Defines cell’s shape • Facilitates shape changes • Enables cell movement • Directs organelle movement

  3. The Three Main Subunits

  4. Microtubules • Structure • Protein subunits • Function • Maintains cell shape • Moves chromosomes during cell division • Moves cells about– flagella and cilia

  5. Microtubules – maintain cell shape

  6. Microtubules – moving chromosomes

  7. Microtubules – moving cells with flagella and cilia

  8. Microfilaments • Composition • Actin – protein double strand • Function • Maintain Shape • Motion - pseudopodia / cytoplasmic streaming • Contraction – cleavage furrow / muscle

  9. Microfilaments – maintain shape

  10. Microfilaments - motion • Motion - pseudopodia / cytoplasmic streaming

  11. Microfilaments - contraction Cytokinesis muscle contraction

  12. Intermediate Filaments • Composition • Keratins – a family of proteins • Function • Reinforce cell shape
