Exemplars of each phyla of protozoa



 Find exemplars of each phyla of protozoa. Get their picture and label them. Also describe their differences and unique structures.


Sporozoans
They are from spores which are from fungi, and they are able to survive in extreme conditions. Many protozoans are sporozoans. An example is the Malaria disease which originated in Africa.


Ciliates
They use their short bristles attached to their body called cilia to swim through a body of water. One of the best known is paramecium. 


Amoebas


They move using their extension of their cell membrane(pseudopods). They do not have cilia which are bristles attached to their bodies like Ciliates. They have this special spine that is covered in shells that allow themselves to catch prey. 






Flagellates
They move through a body of water using their long cilia which are also known as flagellas. They were classified as green algae because of their color and because they are mostly found in ponds with other bacteria. They have thick membrane (dinoflagellates) and are not protozoa but plant cells.
