Kingdom Protista

Protists

• Protista is made up of mostly unicellular organisms that do not fit into any other kingdom

• Can be heterotrophic or autotrophic• Most live in water or moist

environments• ALL are eukaryotic• Protista = the very first

Classification

• Classified according to how they obtain nutrition and how they move

1. Animal-like Protists2. Plant-like3. Fungus-like

Animal-like Protista

• Also called Protozoa• Classified by the way they move into

4 different phyla1.Zooflagellates – flagella2.Sarcodines – pseudopodia (Amoeba)3.Ciliates – cilia (Paramecium)4.Sporozoans – do not move

(Plasmodia)

Plant-like Protists

• Contain chlorophyll and perform photosynthesis

• They can be either unicellular or multicellular

• Many contain pigments that give them a variety of colors

• Examples: Euglenoids, Algae, Diatoms, Dinoflagellates

Algae

• Make up the base of aquatic food chains

• Phytoplankton make up half of the photosynthesis that occurs on earth

• Can cause “red tides” or algal blooms that are toxic

Unicellular: plankton, Euglena Multicellular: Green algae, Brown algae,

Red

Algae

Unicellular Organisms

Fungus-like Protista

• Decomposers that live on dead organic matter

• Usually found under fallen leaves or rotting logs
