Kingdom Protista3 GROUPS OF PHYLA: ANIMAL-LIKE, PLANT-LIKE AND FUNGAL-LIKE

PROTISTS ARE: UNICELLULAR, COLONIAL, OR MULTICELLULAR; EUKARYOTIC; MOSTLY HETEROTROPHIC; NOT DISTINCTLY PLANT OR ANIMAL

Animal-Like Protists- heterotrophic

Animal like protists are categorized according to their method of movement. Phylum Sarcodina- pseudopods

Phylum Mastigophora/Zoomastigina- flagellum

Ciliophora- cilia

Sporozoa- no movement (just through spores)

Phylum Sarcodina

Free living (freshwater, saltwater, soil)

Some are animal parasites

Can move with the aid of a pseudopod (false feet)- move by cytoplasmic extensions and retractions of the pseudopod

Engulfs food

Ex. amoeba

Phylum Zoomastigina

Live in freshwater or salt water

Parasitic and disease-causing

No sexual reproduction, mostly use fission (asexual)

Form cysts and spread from host to host

Ex. Trypansoma (sleeping sickness)

Phylum Ciliophora

Most complex of this kingdom; most advanced

Cilia on body (hair-like projections) help organism ‘swim’

Reproduce asexually through binary fission and sexually by conjugation

Ex. paramecium

Phylum Sporozoa

Need host to move around

Ex. Plasmodium that causes Malaria

CYCLE: mosquito human liver red blood cells blood cell breaks spreads to more cells

Plant-Like Protists

Often referred to as algae Can exhibit characteristics of both plants and animals Are plant-like because they have cell walls and

chlorophyll Reproduction can be sexual or asexual

Phylum Chlorophyta

The Green Algae

Phylum Pyrrophyta

Fire-algae

Produce light

dinoflagellates

Phylum Rhodophyta

Red Algae

Phylum Chrysophyta

Golden Brown Algae

Phylum Phaeophyta

Brown Algae

Kelp

Phylum Euglenophyta

Animal and plant-like features: Chloroplasts

Engulfs food

Flagella

Ex. euglena

Fungal-like ProtistsPhylum Myxomycophyta/Myxomycota

Called slime molds

Body is called plasmodium

Constantly changing shape
