1. Kingdom Protista

2. Kingdom Protista Eukaryotic “Catch-all” Kingdom
Contains organisms that resemble organisms in the kingdoms animalia, plantae, and fungi.
Can be autotrophs or heterotrophs.
Can be unicellular or multicellular.

3. Animal-like Protists: Protozoans
What’s a flagella????
Phylum Zoomastigina (Zooflagellates)
Swim using one or two flagella
Absorb food through the cell membrane
Reproduce asexually (mitosis) or sexually
Live in lakes, or streams, can be parasitic

4. Animal-like Protists: Protozoans
A temporary cytoplasmic extension
Phylum Sarcodina (Sarcodines) –
Move and feed by using a pseudopod.
Movement is called “amoeboid movement”
Contain a food vacuole.
Reproduce asexually (mitosis)
Most common example: amoeba
What is a vacuole???

5. Animal-like Protists: Protozoans
Small hair-like projections
What is conjugation???
Phylum Ciliophora (Ciliates) –
Feed and move using cilia
Reproduce by conjugation
Live in fresh and salt water, can be parasitic.
Common example: paramecium

6. Animal-like Protists: Protozoans
Phylum Sporozoa (Sporozoans) –
Do not move on their own
Parasitic
Have a complex life cycle that involves more than one host.

7. A carbohydrate found in the cell wall of fungal organisms
Fungus–like Protists
Heterotrophs that absorb nutrients from dead or decaying matter.
Lack chitin in cell walls.
2 types:
Slime molds
Water molds
A carbohydrate found in the cell wall of fungal organisms

8. Plant-like Protists: Unicellular Algae
Phylum Euglenozoa (Euglenophytes)
Have two flagella
Have a pellicle
Have an eyespot that directs light to chloroplast
Reproduce asexually
Specialized cell wall

9. Plant-like Protists: Unicellular Algae
Phylum Chrysophyta (Chrysophytes)
Have gold-colored chloroplasts
Store food in the form of oil instead of starch
Reproduce sexually and asexually

10. Plant-like Protists: Unicellular Algae
The main component of glass
Phylum Heterokontophyta (Diatoms)
Have cell walls made of silicon
Shaped like two sides of a petri dish

11. Plant-like Protists: Unicellular Algae
Phylum Dinoflagellata (Dinoflagellates)
50% autotrophs, 50% heterotrophs
Have two flagella
Reproduce asexually
Many are luminescent
Can cause “red tide”
They glow!!!

12. Plant-like Protists: Red, Brown & Green Algae
Phylum Rhodophyta (Red Algae)
Live at great depths
Contain reddish accessory pigments called phycobillins
Mostly multicellular
Contain flagella

13. Plant-like Protists: Red, Brown & Green Algae
Phylum Phaeophyta (Brown Algae)
Contains brown accessory pigment called fucoxanthin.
Largest and most complex algae
Multicellular
Most are marine
Largest algae – giant kelp

14. Plant-like Protists: Red, Brown & Green Algae
Phylum Chlorophyta (Green Algae)
Share many characteristics with plants
Found in fresh and salt water
Most live most of life as unicellular
Reproduce through a process called alternation of generations
Switch between haploid and diploid stages during their life cycle

15. Human Uses of Algae
Produce much of the Earth’s oxygen through photosynthesis
Chemicals in algae are used to treat stomach ulcers, high blood pressure and arthritis
Used to make sushi rolls, ice cream, salad dressing, pudding, candy bars, pancake syrup and eggnog
Used to make plastics, waxes, transistors, deodorants, paints, lubricants and artificial wood.
