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 LyTsU

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 om/watch?v=OUeAMz oKNWg

Chrysophyta Approx. 10,000sp Unicellular Fresh & marine habitat Silica glass shells Benefits: photosynthetic –Diatomaceous Earth –Cleaners & filters Yellow or brown Ex. Diatoms 0iWM_lWM

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 bfkDA4

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

Sporozoa no locomotion all parasitic Causes coccidiosis – diarrhea, vomiting, weight loss

Sporozoa

Zoomastigina * Flagella Giardia Trypanosoma Volvox 1WkFc&feature=related

Sarcodina * Pseudopodia – “false feet” **Example: Amoeba
