  1. Cilia and Flagella in Cell Structure By: Tim Potter & Lou Ruspi

  2. Cilia • Small, hair like organelles used for locomotion • Only found in eukaryotic cells • Similar to eukaryotic flagella

  3. Flagella • Larger/longer than Cilia, whip-like tail appearance • Three general kinds, Bacterial and Archaeal (corkscrew), and Eukaryotic (whip, similar to cilia) • Flagellum of male sperm is a modified cilium

  4. Bacterial and Archaeal Flagella

  5. Eukaryotic Flagella

  6. Diseases • Ciliary defects can lead to a large variety of diseases • Primary Ciliary Diskenisia, Polycistic Kidney Disease, Bardet-Biedl Syndrome, ectopic pregnancy, and male infertility

  7. Question 1What is a disease caused by Cilia • Androgenic Alopecia • Cholelithiasis • Ectopic Pregnancy • A & B • A & C • None of the above

  8. Question 2How do Cilia and Flagella differ in locomotion? • Some Flagella use corkscrew motions • Cilia must move in groups • All Flagella have hollow tubes, and use base “motors” to move • A and B • B and C
