7. CENTRIOLES

8. nucleus

9. Like Cilia and Flagella, Centrioles are also made of microtubules. The difference is that they contain 9 sets of triplets and no doublet in the center. How the triplets in the basal body turn into the cilium doublet remains a mystery. Centrioles come in pairs, each organized at right angles to the other. Centrioles organize the spindle apparatus on which the chromosomes move during mitosis. source: http://cellbio.utmb.edu/CELLBIO/cilia.htm Image: http://www.edu.ipa.go.jp/ chiyo/HuBEd/HTML1/en/3D/cell.html

10. KINETOSOME

11. c = cilia Kinetosomes, also known as basal bodies, are specialized centrioles found at the base of both cilia and flagella. They help with the formation of cilia and flagella. bb = kinetosomes

12. cilia

14. Ciliated epithelium in human trachea Ciliated marine protist Cilia are used to move fluids. Protists use them to swim or to create feeding currents. Multicelled animals use them to move the mucous out of the nasal passages.

15. FLAGELLUM kinetosome

16. What are flagella? Many single-celled organisms use so called flagella (also named undulipodia) for swimming. These are whip-like structures that act like a propeller. Some groups have one, others have two. Shown here is a photosynthetic flagellate protozoan: Euglena, and a common marine dinoflagellate, Noctiluca.
