Presentation Transcript

  1. Cilia, Flagella, & Microvilli By: Sydney Collier & Morgan Martin

  2. Cilia • Function: Moves substances over the surface of cells. • Location: around the cell’s body • Found: W. Sharpey in 1835 found that cilia and flagella are active organelles • Affect on the body:Protects the nasal passageways and filters out dust and other particles that enter the nose with breathed air.

  3. Flagella • Function: Much bigger than cilia and propel sperm cells • Location: in the cytoplasm • Found: W. Sharpey in 1835 found that cilia and flagella are active organelles

  4. Microvilli • Function: Increase the surface area of cells and aid in absorption and secretion • Location: the cell membrane • Found: Although the primary cilium was discovered in 1898, it was largely ignored. Only recently has great progress been made in understanding it • Affect on the body: Aids the migration of white blood cells
