Have you know about PROTIST?
Lets learn about protist together…
Eukaryotic
Unicellular, colonial, and multicellular.
Protist is…
Five Supergroups of Eukaryotes…
Classification of Protista…
Excavllta…
Diplomonads and
Parabasalids
Euglenozoans
Excavllta…
Diplomonads and
Parabasalids
DiplomonadsCannot use oxygen to help extract energy from carbohydrates and other organic molecules.Multiple flagella.Parasites.
Giardia intestinalis
Cause severe diarrhea.
Excavllta…
Diplomonads and
Parabasalids
ParabasalidsHave reduced mitochondria.Generate some energy anaerobically.releasing hydrogen gasas a by product.
Trichomonas vaginalis
Infect the vagina.
Excavllta…
Euglenozoans
KinetoplastidsSingle, large mitochondrion kinetoplastFeed on prokaryotes in fresh water, marine, and most terrestrial ecosystems, as well as species that parasitize animals,plants, and other protists.
Trypanosoma
Cause sleeping sickness .
Excavllta…
Euglenozoans
EuglenidsOne or two flagella.Mixotrophs.Phagocytosis.
Chromalveolata…
Stramenopiles
Alveolates
Chromalveolata…
DinoflagellatesReinforced by cellulose plates.Two flagella.Marine and freshwater.“red tide” phenomenon.
What is RED TIDE???
Pfiesteria shumwayae
Alveolates
Do you think it’s a beautiful phenomenon?Check this video
RED TIDE
This video ilustrated the effect of “red tide” phenomenon.
Chromalveolata…
Apicomplexans Parasites.Sexual and asexual stages.Require two or more host species.
Life Cycle
Plasmodium
Alveolates
Chromalveolata…
CiliatesUse cilia to move and feed.Micronuclei and large macronuclei.
Feeding, waste removal, and water balance.
Conjugation and reproduction.
Alveolates
Feeding, waste removal, and water balance.
Conjugation and reproduction.
Chromalveolata…
Stramenopiles
DiatomsUnicellular.Have a unique glass-like wall made of hydrated silica (silicon dioxide).Asexually by mitosis.Cysts.
Chromalveolata…
Stramenopiles
Golden AlgaeYellow and brown carotenoids.Biflagellated.Fresh water and marine.Photosynthetic and mixotrophic.Unicellular, but some are colonial.
Dinobryona colonial golden alga found in fresh water
Chromalveolata…
Stramenopiles
Brown AlgaeMulticellular.Marine.Brown or olive color to the carotenoids.Called “seaweeds”.Cell walls are composed of cellulose and gel-forming polysaccharides.
Laminaria

Chromalveolata…
Stramenopiles
OomycetesWatermolds, the whiterusts, and thedowny mildews.
Laminaria
Life Cycle
Rhizaria…
Forams
Radiolarians
Rhizaria…
Forams
Foram tests consist of a single piece of organic material hardened with calcium carbonate. Forams are found in both the ocean and fresh water. Ninety percent of all identified species of forams are known from fossils.
Rhizaria…
Radiolarians
Symmetrical internal skeletons that are generally made of silica.Marine.
Archaeplastida…
Red Algae
Green Algae
