1. Kingdom Protista

2. Protists
Contain a very diverse group of organisms that are had to classify!
ALL EUKARYOTIC
Can be unicellular OR multicellular
Unicellular – ONE cell
Multicelluar – MANY cells

3. 1. Animal-like Protists Known as PROTOZOANS
Many are parasites, living in water, in soil and on other organisms
They have special structures for movement!

4. Structures of Movement
Flagellum: Long projection that looks like a tail
Pseudopods: Projections of cytoplasm to capture food and move
Cilia: Short hair-like projections for movement and feeding

5. Watch and See Go to www.missconnelly.weebly.com Click on Biology
Click on Unit 11 – Living Organisms
In the Protist Section – play each video to see how each structure causes movement
At the very bottom, listen to the raps…can you do better? - EARLY FINISH – you and a partner(s) create your own rap!

6. Did you observe closely?
Which organism has which structure?
Structure: Flagella Organism: ___________
Structure: Pseudopods Organism: ___________
Structure: Cilia Organism: ___________
Structure: Eyespots Organism: ___________
Make sure you put this in your notes!

7. 2. Plant – like Protists Known as Algae
Contains chloroplast and can perform photosynthesis
Also have cell wall, flagella, and eyespots
Many different types! Including diatoms (produce silicon), dinoflagellates (two flagella), euglenas (unicellular), red algae, brown algae (seaweed), green algae (very similar to plants).

8. Make sure you know the examples…
Diatoms
Dinoflagellates
Euglena
Red Algae
Green Algae
Brown Algae - Seaweed

9. 3. Fungi-like Protist
Heterotrophs that get their food from decomposing organisms
Have cell walls
Examples: Slime molds, water molds, some mildews
Make sure you know the examples

10. Take a look
Slime mold
Mildew
Water Mold

11. Do you remember STERN GRR? (mini review)
Watch the video by clicking the link below
The BIOLOGY SONG
I know ya’ll have been waiting on this…
All LIVING things do STERN GRR!!

12. Protist Life Processes STERN GRR
Synthesis
Some can do photosynthesis (make it’s own food (glucose) from the sun)
ALL do PROTEIN SYNTHESIS and build organic molecules
Transport
Use DIFFSUION and OSMOSIS to regulate levels of water, gases, and molecules

13. Takes in CO2 and O2 through diffusion Growth
Excretion
Gets ride of wastes through an anal pore
Respiration
Takes in CO2 and O2 through diffusion
Growth
Grow using mitosis – identical cells

14. Nutrition Reproduction Regulation Can be autotrophic or heterotrophic
Can consume food through oral groove
Reproduction
Can reproduce sexually and asexually
Regulation
Controls what goes in and out of the cells using a contractile vacuole (expands by sucking things in or contracts by squeezing things out)

15. Adaptive Behaviors of Protist
Eyespots – responsible for phototaxis
Phototaxis – movement of an organisms towards or away from light.
If there is a lack of light or too much light, the organism with eyespots must ADAPT in order to survive

16. Protists also respond to food
Chemotaxis – organisms moves towards or away from food/substances needed for survival.
Example: dinoflagellates
