1. Protists!!!

2. Protists
Protists can be defined as single-celled organisms that contain a nucleus

3. Protists Protists live in: Watery environments Moist soil
Live inside larger organisms

4. Protists Characteristics Can be autotrophic or heterotrophic
Most live as individual cells
Some live in large colonies

5. Protists
3 Major kinds of Protists
Animallike
Plantlike
Funguslike

6. Protists The animallike protists are broken down into 4 major groups
Sarcodines
Ciliates
Zooflagellates
Sporozoans

7. Sarcodines
Sarcodines can be identified by their pseudopods or “false-foot”
Pseudopod is a footlike extension that an amoeba uses to move and capture food
Ex. Amoeba
(NNN) VIDEO!!!

9. Ciliates
Ciliates have small hairlike projections on the outside of their cells
Cilia act like tiny oars to move the organism
Ex. Paramecium
Stentor, Spirostomum

10. Zooflagellates
Zooflagellates are animallike protists that move using a flagella (usually 1-8 flagella)!
Many kinds live inside other organisms as symbionts a few are parasites
Ex. Giardia

11. Sporozoans
All sporozoans are parasites that feed on the cells and body fluids of their host animals
Ex. Plasmodium malaria

13. Plantlike Protists
Plantlike protists capture energy from the sun using chloroplasts

14. Plantlike Protists Three major groups of plantlike protists Euglenas
Diatoms
Dinoflagellates (WHICH IS WHICH????)

15. Euglena
All possess two flagella, eyespots (why?!), and green structures used in photosynthesis

16. Diatoms
Diatoms are plantlike protists made of a tough glasslike, silicon material

17. Dinoflagellates
Dinoflagellates are plantlike protists that have two flagella and armor like cell walls

18. Fungus-like Protists
Fungus-like protists are heterotrophic, have cell walls, and use spores to reproduce. An example are slime molds.

19. Adios, amoebas…
