1. Protist Kingdom

2. What is the Difference Between Prokaryotic and Eukaryotic?
2. Prokaryotic cells lack membrane-bound organelles such as a mitochondria and chloroplast; Eukaryotic cell have them.
Prokaryotic cells have no nucleus; Eukaryotic cells do

3. Protist Habitat: Freshwater (ponds, rivers, streams, etc)

4. Protist Habitat: Marine (Ocean)

5. Protist Habitat: Soil

6. Protist Habitat: In other organisms

7. Protozoa: Animal-like Protists AKA: Zooplankton

8. Zooplankton: Paramecium

9. Paramecium Structure
Paramecium are unicellular

10. Paramecium Information*
Move using Cilia – tiny hairs covering the outermost layer

11. Paramecium Information
ALL aquatic protists contain a contractile vacuole
Acts like a water pump which regulates the water pressure inside organism

12. *

13. Method of Feeding* Heterotroph
Cilia helps guide food into the gullet; a food vacuole is formed; digestive enzymes break down food

14. -One parent -Doesn’t exchange DNA -Produces identical offspring
Reproduction: Binary Fission (Asexual)*
-One parent -Doesn’t exchange DNA -Produces identical offspring

15. Reproduction: Conjugation(Sexual)
Reproduction: Conjugation(Sexual)* Two parents Exchange DNA Produce different offspring

16. Zooplankton: Amoeba

17. Amoeba Structure
Amoeba are unicellular

18. Move using Pseudopod – False food Literally moves like a blob
Amoeba Information*
Move using Pseudopod – False food
Literally moves like a blob

19. Pseudopod surrounds food; process called Phagocytosis
Method of Feeding*
Heterotroph
Pseudopod surrounds food; process called Phagocytosis
Eventually engulfs it
Fast forward to 1:15

20. -One parent -Doesn’t exchange DNA -Produces identical offspring
Reproduction: Binary Fission (Asexual)
-One parent -Doesn’t exchange DNA -Produces identical offspring

22. Protozoa: Plant-like Protists AKA: Phytoplankton

23. Phytoplankton: Euglena

24. Euglena Structure
Euglena are unicellular

25. Euglena Information Move using a Flagella; a long whip-like tail
Different species of euglena move in different ways

26. *They can spin like a tornado

27. *They can move like a worm

28. Method of Feeding Autotroph and Heterotroph
Can undergo photosynthesis; has an eyespot to act as a sunlight sensor
Also can consume food if necessary

29. -One parent -Doesn’t exchange DNA -Produces identical offspring
Reproduction: Binary Fission (Asexual)
-One parent -Doesn’t exchange DNA -Produces identical offspring

30. Phytoplankton: Dinoflagellates
Dinoflagellates are Unicellular

31. Some have the ability to bioluminescence (glow)
The ability to glow is similar to a burglar alarm or defense system

32. Video #1: Splashing Water (Turn Volume Down)
Video Clip #2: Surfing

33. Phytoplankton: Diatoms
Diatoms are Unicellular

36. -Diatoms cell wall contains silica (glass)
-When they die their silica shells fall to ocean floor. It becomes diatomaceous earth

39. Phytoplankton: Green Algae
Unicelluar; Multicellular; Colonial (many individual organisms living together in a outer membrane)

40. Most diverse group of protists; can be found
everywhere

41. Even on the backs of some animals

42. Phytoplankton: Brown Algae
Not a true plant because it lacks TRUE roots, stems, and leaves
Frond≠Leaf
Stipe≠Stem
Holdfast≠Roots

43. Seaweed is an example of Brown Algae

44. Kelp is also an example of Brown Algae

45. Brown Algae is Edible
