KINGDOM PROTISTA
Write what is underlined
Chapter 20

2. WHAT IS A PROTIST?
Any eukaryote that is not a Plant, Animal, or Fungi.

3. KINGDOM PROTISTA CHARACTERISTICS
Eukaryotes
Unicellular and Multicellular
Autotrophic or heterotrophic
Some have cell walls
Many have structures specific for movement.

4. TYPES OF PROTISTS Animal like Protists Plant like Protists
Funguslike Protists

5. ANIMAL-LIKE PROTISTS Typically heterotrophic, motile, unicellular
Live in water but can be found in moist soil
Grouped by method of locomotion

6. PHYLUM ZOOMASTIGINA: ZOOFLAGELLATES
Move by flagella
Live symbiotically
Examples:-
Trichonympha collaris – termites
Tyrpanosoma brucei – tsetse fly cause sleeping sickness

7. SARCODINES Amoeba Unicellular Move by pseudopods “false foot”
Feed by phagocytosis
Can cause dysentery

8. PHYLUM CILIOPHORA: CILIATES
Paramecium
Use cilia for feeding and movement.
Discharge trichocysts to disable prey
Reproduce sexually and asexually

9. PHYLUM SPOROZOA Nonmotile parasites Form spores Example:-
Plasmodium vivax causes malaria
Infected female Anopheles mosquito
Cells bursts, high fever and severe chills

10. MALARIA

11. PLANTLIKE PROTISTS
Chlorophyll and accessory pigments allow algae to harvest and use the energy from sunlight.

12. Plant like Protists - Algae
Live in water and photosynthesize (produce much of the earths oxygen)
Named for the type of chlorophyll and accessory pigments they contain - Green, golden brown, brown, and red
Produce food that maintain communities in oceans and fresh water
Chemicals from algae are used to make plastics, waxes, paints, deodorant. Also used to make ice- cream, salad dressing, pudding, or a candy bar.

13. Red, Brown, and Green Algae
Red Algae:- live at great depths due to their efficiency in harvesting light energy. Red algae contain chlorophyll a and reddish accessory pigments called phycobilins.
Brown algae:- contain chlorophyll a and c, as well as a brown accessory pigment, fucoxanthin.
Green Algae:- share many characteristics with plants, including their photosynthetic pigments and cell wall composition.

14. Euglenophytes: Euglena
Chloroplast
Carbohydrate storage bodies
Gullet
Pellicle
Contractile vacuole
Flagella
Eyespot
Nucleus
Unicellular
Moves by flagella
Heterotrophic or autotrophic

15. DIATOMS
Produce cell walls rich in silica (Si – the main ingredient in glass)

16. DINOFLAGELLATES
Half are photosynthetic and the other half are heterotrophic.
Two flagella that cause it to spin like a top
Warm surface waters cause “blooms”
Red tide can paralyze humans

17. Unicellular Green Algae Chlamydomonas
Colonial Green Algae Volvox
Unicellular Green Algae Chlamydomonas
Filamentous Green Algae Spirogira
Multicellular Green Algae
Multicellular Red Algae

18. FUNGUS LIKE PROTIST Lack chlorophyll
Absorb dead and decaying organic matter.
Not classified as true fungi as they do not contain chitin their cell walls.

19. Examples:-
Slime molds are fungus like protists that play key roles in recycling organic material
Oomycetes thrive on dead or decaying organic matter in water and are plant parasites on land.
