HOW PROTOZOA MOVE - FLAGELLATES, CILIATES AND RHIZOPODS

 As you know protozoa are unicellular, heterotrophic living things often found in water, damp places or in other organisms, because some are parasites. They are eukaryotic cells and are classified by the way they move.
Watch this collection of short videos where you can see protozoa moving in different ways. The first one is an amoeba that moves by stretching its membrane in different directions. Its elongated membrane is called a pseudopod which literally means `false legs´.
            AMOEBA ARE RHIZOPODS
Paramecium is surrounded by tiny hairs called cilia, that they use to move. Paramecium are therefore ciliates.
PARAMECIUM ARE CILIATES
 This second video has been taken with a powerful 3D microscope and here you can see the cilia better.
CILIATES
In the next video you can see two flagellates. These protozoa move with a tail called a flagellum.
  THESE ARE FLAGELLATES
