Protozoa

Amoeba

Protozoa are unicellular organisms. Protozoa can be subdivided in to Rhizopods, Ciliates, flagellates and sporozoans.

                  Rhizopods can move by means of pseudopodia. They also catch their prey by means of these catch their prey by means of these pseudopodia.

  

eg. Amoeba.

 

Microscopic hairs called cilia are present around the cell in ciliates. They use these cilia for feeding and movement. Paramecium is an example for ciliates.

 

Fatciliate protoza

eg. Paramecium

 

Flagelates have a whip like hair called a flagellum. These protozoa have chlorophyll and can synthesize food by photosynthesis.

 

eg. Euglena 

Sporozoans produce spores and are internal parasites with complex life cycles.

eg. Mallaria causing plasmodium
