PPT-Cillia and Flagella

Cillia and Flagella John Bassili amp Zheeanna Zahid Structure Of Cilia Cilia are slender microscopic hair like structures that extend from the surface of nearly all multiple or single cells. 1 see also the Primary Cilia Resource web pag Although these highly con served structures are found across a broad range of species a nearly ubiquitous appearance is observed only in vertebrates Cilia can be structurally divided into subcompartmen . Burnside, Glenn, . Vanscoy. , White, Conrad. Actin. Filaments . Actin Filaments. Main Function: to help the contraction of cells . Found in: eukaryotic cells only. If Actin filaments were not present: myosin molecules would be scattered throughout the cell, and the cell would very disorganized and . Motility is closely linked with chemotaxis, the ability to orientate along certain chemical gradients.. A large number of bacteria are motile. . . Most . possess one or more flagella on their surface that allow them to swim. . By Kevin Partlow, Neil Perry, and Chris . Paszkiewicz. Cilia and Flagella. Cilia-numerous minute hair like organelles. Flagella-identical to the cilia but there is less of them and they are smaller. Location and Functions. MBIO . 460. Lecture 4. Dr. . Turki. . Dawoud. 2. nd. Semester. 1436/1437 H .

The third type of protozoan's are called zooflagellates.. It is an animal like protist that has flagella.. Most of the zooflagellates have one to eight flagella, to help them move..

Cilia are hair-like organelles located on the outside of eukaryotic cells.. There are motile cilia and non-motile cilia.. Motile cilia move in a wave-like motion to move particles across the surface of the cell, or to allow unicellular organisms to move.. :. contain enzymes that transfer . hydrogen. from various substrates to . oxygen. ..
