The kingdom
protista is the most diverse of all kindoms. It is composed of microscopic
eukaryotic organisms, which are often hard to put in another kingdom. It is divided into 3 categories:
1.
Protozoans
2.
Algae
3.
Slime Molds and
Downey Mildew
1. The genus protozoa is composed of those protists who are most like animals. It is divided further into:
Ciliophora: protists who move using
cilia, tiny hair like structures.
Zoomastigina: protists who move using
flagella, longer whip like structures
Sarcodina: protists who move using
pseudopodia, extentions of their
cytoplasm
Sporozoa: protists who are non-
motile and generally live as parasites
2. Algae are protists that are most like plants. They are divided as follows:
Euglenophyta: special protists that are both
autotrophic and
heterotrophic and use
euglenoid movement.
Baciliariophyta: protists with a Silicon Dioxide shell which make up most
phytophlankton. ex. Diatoms
Dinoflagellates: protists with a cellulose shell which use flagella to move.
Chlorophyta: green algae w/ pigment
chlorophyll
Rhadophta: red algae w/ pigment
phycobilin
Phaophyta: brown algae w/ pigment
fucoxanthin
3. Slime molds and downey mildew are the really strange of the really strange. They are divided as follows:
Myxomycota:
cellular slime molds
Acrasiomycota:
plasmodial slime molds
Oomycota: downey mildews and water molds
