By Justin Borsdam & Zach White Flagella & Cilia By Justin Borsdam & Zach White

Flagella & Cilia Flagella Cilia Whip-like appendages of cells that are the main source of movement in Eukaryotic cells. Flagella 1-2 Long appendages Tail like appendage. Cilia Several short appendages. Usually lines the cell.

Structure Undulipodium – (9+2 organelle) Basal Body Plasma Membrane 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

Function The 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, Sperm Ectopic Pregnancy Male Infertility Polycystic Kidney Disease Retina Degeneration Situs Inversus Cilial function is responsible for the normal left-right asymmetry in mammals.

Question#1 Flagella and Cilia are the main source of _________ in Eukaryotic cells. Digestion Movement Protein Food

Question#2 Cilia are made up of… 1-2 long tail-like appendages. 1-2 short tail-like appendages. Several short tail like appendages. Several short appendages lining the cell.
