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
