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

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.
