1. Protists!!!

2. Protists

Protists can be defined as singlecelled 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, ameobas…
