1. Chapter 22 Protist Protist Diversity Protozoan: Animal-like Protists
22.2 Algae: Plant-like Protists
What are Algae?
Phyla of Algae
Reproductive strategies of Algae Fungus-like Protists

2. Chapter 22 Protist continued
22.3 Different Kinds of Fungus like Protists
Slime Molds
Water Molds and Downy Mildews

3. Protist Diversity Most Diverse of all five kingdoms
size varies from microns to over 100 meters
200,000 species
All are Eukaryotes

4. Protozoan: Animal-like Protists
Unicellular heterotrophs
classified by their method of movement
cilia
flagella
pseudopodia
non-motile

5. Animal - like Amoebas Phylum sarcodina No wall outside cell membrane
move by forming pseudopodia
live in water or wet patches
have problem with Osmosis
Contractile vacuoles are Use to eliminate waste

6. Amoebas pictures

7. Amoebas with Shells
Hard Shell Amoeba

8. Amoeba feeding

9. Ciliated Protist
Paramecium

10. Paramecium morphology

11. Paramecium feeding

12. Flagellated Protist

13. Flagellates: Protozoans that move with Flagella
Animal-like because they move and aren’t able to make their own food
Some have a single flagella and others have two
Are aquatic / marine single cell organisms

14. Non-Motile Protist
Giardia- cause of Malaria

15. Reproductive strategies of Sarcodines

16. Contractile Vacuoles Vacuole filled with waste products
Emptied vacuole waste material

17. 22.2 Algae: Plant-like Protists
Plant like protist that utilize Photosynthesis
Some are unicellular
some are multicellular
All are Aquatic / Marine

18. What are Algae? Six different groups Euglenoid Diatoms Dinoflagellates
Unicellular
Euglenoid
Diatoms
Dinoflagellates
Multicellular
red algae
Brown algae
Green algae

19. Euglenoid

20. Euglenoid Protist They are unicellular Are heterotrophs
Utilize Photosynthesis to make their food
Can absorb food during dark periods
Have and eyespot to help find light
single flagella to swim

21. Euglena- picture 2

22. Euglena diagram

23. Diatoms- protist

24. Diatom - assorted picture

25. Diatom facts
Have two halves to their hard shells which are made of silica
undergo both asexual and sexual reproductions
Vital part of the food chain in oceans

26. Diatom - reproduction

27. Dinoflagellates pictures

28. Dinoflagellate info Unicellular in size
Cell wall is made of thick plates
Move by using two flagella
One species causes Red tide

29. Red algae Picture

30. Red Algae information Another name for this group is red seaweed
acts like and looks plants - attaches itself to the bottom and has a long stem like structure with what looks like leaves.
Deep ocean location because they can absorb blue colors ( most penetrating light)

31. Brown Algae - pictue

32. Brown Algae picture 2

33. Brown Algae information
Another name for this group is Brown seaweed ( kelp)
loves cold water
uses a thallus to attach itself to rocks
no real stem or roots
Agar ( gelleton ) comes from this protist

34. Green Algae - picture

35. Green Algae picture 2

36. Green Algae information
Most are fresh water organism
some are unicellular/ multicellular
Reproduce by using both sexual and asexual reproduction
Use Alternating generation

37. Reproductive strategies of Algae

38. Alternating Generation -diagram

39. 22.3 Fungus-like Protists
Colorfull - ranging in color ( red, blue, violet to yellow
live in cool moist environments
live off rotting organic matter
are motile

40. Different Kinds of Funguslike Protists
There are three phyla of fungus like molds
slime molds
plasmodial
cellular
water molds

41. Slime Molds- plasmodial

42. Slime mold - cellular

43. Water Molds and Downy Mildews
