Kingdom ProtistaKingdom Protista

• Contains the MOST diverse organisms of all the kingdoms!

• ALL are eukaryotes

• Animal-like protists: Protozoa• Plant-like protists: Algae• Fungus-like protists

Protozoans: Protozoans: Animal-like Protists Animal-like Protists

• Unicellular heterotrophs that move in a variety of ways

• 4 groups:– Amoebas– Flagellates– Ciliates– Sporozoans

Protozans: Amoebas

• Form pseudopods to move and feed

• Ex: amoeba

Protozoans: Cilliates

• Move by beating cilia that cover the cell

• Ex: parimecium

Protozoans: Flagellates

• Move by whipping flagella from side to side

• Ex: giardia

Protozoans: SporozoansProtozoans: Sporozoans

• Parasites• Produce spores to reproduce• Ex: plasmodium—causes malaria

Algae: Plant-Like ProtistsAlgae: Plant-Like Protists

• Photosynthetic autotrophs may be uni- or multicellular

• Produce half of the world’s oxygen!

• 2 main groups: unicellular and multicellular

Algae: Plant-Like Protists Algae: Plant-Like Protists • UNICELLULAR

(algae) • Euglenoids

– Flagella• Diatoms

– Made of shells composed silica

• Dinoflagellates– Cell spins b/c of

two flagella

• MULTICELLULAR (seaweed)

• Green Alage– Most diverse

• Red Algae– Deep water

• Brown Algae– air bladders

Fungus-Like ProtistsFungus-Like Protists

• Absorb organic materials and nutrients

• Resemble some types of fungi

Protists and Disease• Giardiasis: causes severe diarrhea and intestinal

cramps that can last for 2-6 weeks• Amebic Dysentery: causes pain, bloody diarrhea,

and fever. Can be fatal if moves into brain• Toxoplasmosis: a small number of people develop

flulike symptoms, dangerous to developing fetuses• Trichomoniasis: STD, women experience discolored

discharge, genital itching, and urge to urinate.• Cryptosporidiosis: severe cramps and diarrhea that

may last up to 2 weeks• Chagas Disease: spread by kissing bugs, and can

cause several heart related issues• Malaria: spread by mosquitoes, causes liver damage

and destroys red blood cells causing fever & Anemia. Can lead to death if left untreated.
