The Odds and Ends Kingdom

2. Characteristics of Protists
Eukaryotes
Autotrophic, Heterotrophic or both
Multicellular and Unicellular
Reproduce sexually and asexually
Live in moist surroundings
Some can move some cannot

3. Three Groups of Protists
Scientists divide protists into categories based on characteristics they share with organisms in other kingdoms
Animal-Like protists
Plantlike protists
Funguslike protists

4. Animal-Like Protists Called animal like because
they are heterotrophs
they are able to move from place to place to obtain food
Another name for animal-like protists is Protozoans
Why not animals?
they are unicellular

5. 4 groups of Animal-Like Protists
Grouped based on how they move and live
Protozoan with Pseudopods (false foot)
Protozoan with Cilia
Protozoan with Flagella
Protozoan that are parasites

6. Protozoan with Pseudopods
Pseudopods means False Foot
Example is an Amoeba

7. Protozoan with Cillia
Cillia-hair like projections from cells that move with wavelike motion
Example is a Paramecium
Reproduces both asexually through binary fission and sexually through conjugation

8. Protozoan with Flagella
Flagella—whip like structure used to move
Live in symbiosis with other organisms
Sometimes helping host, sometimes hurting

9. Protozoan that are Parasites
Feed on the cells and body fluids of a host
Plasmodium is a protozoan that has more than one host and causes malaria
Transferred by mosquitoes

10. Plantlike Protists Commonly called algae Autotrophs
Multicellular and unicellular
Reproduce sexually and asexually

11. Diatoms
Unicellular
Glasslike cell walls

12. Dinoflagellates Unicellular Variety of colors—many glow in the dark
Two flagella to move

13. Euglenoids Green, unicellular, found in freshwater
Autotrophs but can be heterotrophs when sunlight is not available
Has an eyespot and a flagellum

14. Red Algae Almost all are multicellular
Red pigment helps them grow deeper in the water
Used in products such as ice cream and hair conditioner
In Asian cultures it is eaten fresh, dried, or toasted

15. Green Algae Ulva Colony Very diverse Green pigments
Most unicellular—some form colonies and a few are multicellular
Most live in water, some on land
Ulva
Colony

16. Brown Algae Commonly called seaweed Multicellular
Contain brown, yellow, green, and orange pigments
Bladders to float upright

17. Funguslike Protists Heterotrophs with cell walls
Use spores to reproduce
Three types
Slime molds—live in moist soil
and decaying plants
Water molds and downy mildew—live in water and moist places
