  1. Locomotion in Protozoa Zool101Th (Animal Diversity) Prepared by: Dr. Shalini Chouhan RGGDC,Shimla-4

  2. Locomotory Organelles • Locomotion means progression through medium • Pseudopodia • Flagella • Cilia

  3. Pseudopodia • Chracteristic of Sarcodina • Motile • Temporary • Various types • Lobopodia • Filopodia • Reticulopodia • Axopodia

  4. Flagella • Characteristic of all mastigophora • Different type of flagella • Stichonematic e.g. Euglena • Pantonematic e.g. Peranema • Acronematic Chlamydomonas • Pentachronematic e.g. • Simple • Cilia • Myonemes

  5. Modes of Locomotion • Amoeboid or creeping • Swimming • Metaboly /Gliding • Amoeboid movements • Characteristic of sarcodina , certain mastigophora and sporozoa • Well illustrated in Amoeba

  6. Flagellar Movements • Simple conical Gyration • Paddle stroke • Undulating Motion

  7. Ciliary Movements • Ciliates are fastest of all Protozoa • Show effective and recovery stroke • Cilia show synchronous and metachronous beats

  8. Metabolic Movements • Protozoa having myonemes show this type of locomotion/ movements • e.g. Euglena
