What is a Protist?What is a Protist?

Protists are a eukaryotic kingdom.Protists are a eukaryotic kingdom. Almost all protists are unicellularAlmost all protists are unicellular Protists can be defined as any type of Protists can be defined as any type of

eukaryote that is not already eukaryote that is not already classified as an animal, plant, or classified as an animal, plant, or fungi.fungi.

Animal -like protistsAnimal -like protists

Animal type protists are called Animal type protists are called “protozoans”“protozoans”

Each type of animal-like protists are Each type of animal-like protists are classified into different phyla by the classified into different phyla by the way they move.way they move.

The different phyla of animal protists The different phyla of animal protists include: Zoomastigina, Sarcodina, include: Zoomastigina, Sarcodina, Ciliophora, and Sporozoa.Ciliophora, and Sporozoa.

Now, how do they move?!Now, how do they move?!

ZoomastiginaZoomastigina protists use a protists use a “flagella“flagella” to ” to move. This move. This structure is a long structure is a long string-like structure string-like structure and allows for any and allows for any of their movement.of their movement.

Now, How do they move?!Now, How do they move?!

SarcodinesSarcodines move by move by the use of cytoplasm the use of cytoplasm projections. This may projections. This may be seen when looking be seen when looking at a moving ameba: at a moving ameba: psuedopodiapsuedopodia

SporozoansSporozoans move by move by the use of tiny cells the use of tiny cells called “spores”. When called “spores”. When using these spores, using these spores, sporozoans can move sporozoans can move from host to host.from host to host.

Now, how do they move?!Now, how do they move?!

CiliatesCiliates move by move by the use of the use of “cillia” “cillia” which are tiny hair-which are tiny hair-like projections like projections that wave across a that wave across a surface to allow surface to allow movement.movement.
