Presentation Transcript

  1. Cell Motility: • Cell motility or cell movement (2 types) • Movement of the entire cell by Cilia/Flagella • Structures moving within the cell - Motor Protein

  2. Components of the Cytoskeleton: • Microtubules • Tubulin subunits • Cell division and movement • Microfilaments • Actin subunits • Movement and shape

  4. Components of the Cytoskeleton: • Intermediate Filaments • Only in animal cells of specific tissues • Mechanically strengthen cells or cell parts and help maintain shape • Six known groups

  5. Structural Basis of Cell Motility: • Three Mechanisms • Parallel microtubules slide in opposite directions • Microtubule Movement • Shunting of organelles • Shunting organelles 1 • Shunting organelles 2 • Length of microtubule or microfilaments can change due to rapid assembly and disassembly of subunits making up the tubules or filaments
