Flagella & CiliaBy Justin Borsdam & Zach White

Flagella & CiliaWhip-like appendages of cells that are the main source of movement inEukaryotic cells.

•Flagella• 1-2 Long appendages• Tail like appendage.

•Cilia• Several short appendages.• Usually lines the cell.

Structure Undulipodium – (9+2 organelle)

Characterized by 9 fused pairs of microtubule doublets surrounding 2 central single microtubules

Basal Body Cilia/Flagella grows from, and is attached to.

Plasma Membrane Surrounds the flagella

FunctionThe organization of Flagella/Cilia allows

microtubule to slide against one another and causes a bending movement.

This allows cells to do things such as swim, or move water across the surface of the cell.

Examples

Cilia

Diseases (Ciliopathy)Primary Ciliary Dyskinesia

Respiratory Tract, Fallopian Tube, SpermEctopic PregnancyMale InfertilityPolycystic Kidney DiseaseRetina DegenerationSitus Inversus

Cilial function is responsible for the normal left-right asymmetry in mammals.
