Kingdom Protista

• Eukaryotes

• Unicellular and multicellular

• Autotrophic and/or heterotrophic

• Why study them?– Important part of

food chain– Some are parasitic

• Divided into 3 main groups:– Algae– Protozoa– Fungus like

Dinoflagellata• Approx. 1,100 sp• Unicellular• Cell wall composed of

cellulose• Most marine• Contains orange and

yellow pigments• Ex. Fire algae• Harm: Red tide• Benefit: food chain

Chrysophyta

• Approx. 10,000sp• Unicellular• Fresh & marine

habitat • Silica glass shells• Benefits:

photosynthetic – Diatomaceous Earth– Cleaners & filters

• Yellow or brown• Ex. Diatoms

Rhodophyta

• Approx. 4,000 sp.• All multi cellular• Cell wall: cellulose,

caragreenan• Red pigments• Marine (deep waters)• Ex. Red Algae

Phaeophyta

• Approx, 1500 sp.• Multicellular• Cell wall: cellulose,

alginic acid• Brown pigments• Fresh and marine• Benefit: food: rich in

minerals, habitat, food chain

• Ex. Kelp

Euglenophyta

• Unicellular• Approx 1000 sp• No cell wall• Green• Most fresh water• Ex. Euglena• Benefits: producer

Chlorophyta

• Approx. 7,000 sp• Unicellular, colonial,

multicellular• Green• Cell wall made of

cellulose• Soil, rocks, trees, fresh

water• Benefit: food chain,

photosynthetic• Ex.: Spirogyra, volvox

Sporozoano locomotion

all parasitic• Causes coccidiosis – diarrhea,

vomiting, weight loss
