1. The Eukaryotes

2. Eukaryotes Generally larger than prokaryotic cells
Contains a nucleus and other organelles bound by a membrane

3. Eukaryotes The mitochondria and chloroplast:
In terms of cellular organelles, what makes the mitochondria and chloroplast unique?

4. Protista Extremely diverse group of eukaryotes
Range from simple, single-celled organisms to giant, multicellular organisms

5. Protista

6. Protists Mainly aquatic organisms Many are symbiotic organisms
Some are autotrophs
Others are heterotrophs
Many are symbiotic organisms
Know examples!

7. Types of Protists Autotrophs: Undergo photosynthesis similar to plants
Algae (Red, Green, or Brown)
Diatoms: Single-cellular

8. Types of Protists

9. Types of Protists

10. Types of Protists Heterotrophs Ciliates: Flagellates Amoebas:
Move by deforming cell

11. Types of Protists Heterotrophs Apicomplexa: Unicellular
All parasitize animals
Examples:

12. Types of Protists

13. Protist life cycles Simple unicellular organisms
Describe the process by which these organisms undergo reproduction and a process that results in increased genetic diversity.

14. Protist life cycles Multicellular organisms and parasitic organisms
Usually have more complex life cycles
Alternation of generation

15. Life cycle of brown algae

16. Life cycle of Plasmodium
Read figure 14 on page 66 of textbook
Compare this life cycle
with that of brown kelp
