1. Kingdom Protista

2. Protist Characteristics 200,000 species come in different shapes, sizes, and colors eukaryotes All are eukaryotes – have a nucleus and membrane-bound organelles Most are aerobic and single celled All live in a moist environment

3. Kingdom Protista Protists are grouped into three major phyla based on their nutritional needs. 1. Animal-like, the protozoa 2. Plant-like, the algae 3. Fungus-like, the moulds

4. 1. Animal-Like: The Protozoans Heterotrophs Heterotrophs – they ingest or absorb other organisms or dead organic matter Unicellular Unicellular C Classified based on how they move and where they live: A) Flagellates B) Pseudopods C) Cilates D) Sporozoans, primarily parasites

5. 1A) Flagellates: the motorboats Also called zooflagellates Free-living in fresh water or marine habitats flagella Have a whip-like extension called a flagella to move Some cause diseases, including:  Giardia lamblia, which causes upset stomachs and diarrhea.

6. Trichomonas foetus : cow disease

7. Trichomonas vaginalis: an STD

8. 1B) Pseudopods: the blobs Most are free living, also called sarcodines No cell wall pseudopods Move using pseudopods – plasma extensions Engulf bits of food by phagocytosis which involves flowing around and over food particles Reproduce by binary fission

11. 1C) Ciliates: the hairy ones Live in both fresh water and marine habitats. cilia. Move by beating tiny hairs called cilia. Typically reproduce via binary fission, but can also reproduce sexually by conjugation Typically reproduce via binary fission, but can also reproduce sexually by conjugation

13. 1D) Sporozoans: the parasites Non-motile Non-motile - Do not move on their own. host Must live inside a host malaria One type causes malaria http://highered.mcgraw-hill.com/olc/dl/120090/bio44.swf

14. Malaria in red blood cells

15. 2. Plant-Like: The Algae Autotrophic - photosynthetic Can be unicellular, multicellular or live in colonies There are four main groups: A)Algae B)Euglena C) Diatoms D) Dinoflagellates

16. 2A)Algae Are either unicellular or multicellular Are either unicellular or multicellular Are photosynthetic Are photosynthetic chlorophyll Each has chlorophyll Can be red, green or brown Can be red, green or brown No roots, stems, or leaves

18. 2B) Euglena Aquatic Move around like animals Photosynthetic in light Heterotrophic in dark Reproduce asexually by binary fission

20. 2C) Diatoms Have shells made of silica, so are glass-like carotenoids Photosynthetic pigment called carotenoids – give them a golden color

22. 2D) Dinoflagellates Spin around using two flagella Responsible for Red Tides Create toxins that can kill animals and sometimes people

26. 3. Fungus-Like: The Moulds Heterotrophic - feed on dead plants and animals Live in cool, damp habitats Have cell walls Reproduce with spores There are two main groups a) Slime Moulds b) Water Moulds

29. That’s All
