2 Just What are protists?

3 What is a Protist?  Protists are a eukaryotic kingdom.  Almost all protists are unicellular  Protists can be defined as any type of eukaryote that is not already classified as an animal, plant, or fungi.

4 Animal -like protists  Animal type protists are called “protozoans”  Each type of animal-like protists are classified into different phyla by the way they move.  The different phyla of animal protists include: Zoomastigina, Sarcodina, Ciliophora, and Sporozoa.

5 Now, how do they move?!  Zoomastigina protists use a “flagella” to move. This structure is a long string-like structure and allows for any of their movement.

6 Now, How do they move?!  Sarcodines move by the use of cytoplasm projections. This may be seen when looking at a moving ameba: psuedopodia  Sporozoans move by the use of tiny cells called “spores”. When using these spores, sporozoans can move from host to host.

7 Now, how do they move?!  Ciliates move by the use of “cillia” which are tiny hair-like projections that wave across a surface to allow movement.

8 Plant-like Protists  Plant-like protists contain the green chlorophyll pigment.  These protists are able to perform photosynthesis.  There are different phylum of protsits

9 Fungus-like Protists  Fungus-have the ability to absorb food through their cell wall.  Cellular Slime Molds (these molds begin their various life cycles as ameba structures)  Acellular slime molds (these also begin as ameba like structures, however as they reach maturity they develop into one cell with thousands of nuclei)  Water molds (these molds live off of dead/decaying matter, have cell walls made of cellulose, and produce spores)  These are all examples of fungus-like protists  These are all examples of fungus-like protists
