1. PROTISTS EUGLENA, AMOEBA, PARAMECIUM, VOLVOX]\

2. What is a protist? Protist—diverse group of single-celled organisms.
Eukaryotic

3. Euglena Movement- flagellum
Flagella – a whip-like tail that moves quickly back and forth to propel (or move) the protist through water.
Producer- can do photosynthesis to make food
Hunter- captures food
Eyespot – an organelle in the euglena that is sensitive to light
Contractile vacuole collects excess water then shoots it out of the cell.
Reproduction- -asexual (binary fission)

5. AMOEBA Movement- The cell shapes itself into pseudopods (false feet)
Pseudopod – an extension of the cytoplasm that forms when the cytoplasm extends (or stretches out) away from the nucleus. It is used by the amoeba for movement and engulfing its food.
Can be parasite in humans
Reproduction- asexual (binary fission)

7. PARAMECIUM Movement- cilia Cilia – the tiny hairs surrounding the cell
Reproduction- sexual (two parents)
Special feature- two nuclei (macronucleus and micronucleus)
Waste-
Anal Pore (food waste is removed)
Contractile Vacuole (water waste removed)
d for movement.

9. VOLVOX Composed of a colony of more than 50,000 tiny cells
Movement- Many flagella help move the colony.
photosynthesis and flagella help bring in nutrients.
Eyespots sense light.

12. Volvox

13. Amoeba Moves by cytoplasmic streaming
Surrounds food and engulfs it using pseudopods. The food is then stored and digested in vacuoles.`

14. Amoeba Changes shape drastically Heterotrophic
Uses Phagocytosis to surround and engulf it’s food.
Contains Psedopods (False Feet) To move.
Eats bacteria, algae, and other protists
Reproduces asexually

15. Paramecium Most complex and specialized of the protists Unicellular
Contain an oral groove which collects food and swept into it’s mouth. It’s mouth is calle dthe anal pore.
Moves by cilia (hair-like projections)`

16. Paramecium Fast--Can move about 12 body lengths per second
Shape of a pill capsule
Heterotrophic
Relatively large
Common in pond scum and freshwater
Has two nuclei (macro and micro)`

17. Euglena Found in Fresh and Salt Waters
Possesses a RED EYESPOT. This organelle helps with photosynthesis.
Autotrophic and Heterotrophic
Green in color which shows it is made up of chloroplasts when eating autotrophically.
Uses Phagocytosis (engulfing and surrounding it’s food) when eating heterotrophically.

18. Paramecium Uses cilia to sweep food into the oral groove
Feeds on micro-organisms like bacteria, algae, and yeasts
Is covered in cilia so it spirals through water`

19. Volvox A spherical colony of up to 50,000 cells Contains chloroplasts
The colony revolves
Moves and acts as one multicellular organism
but one cell can survive independent of the colony

20. Volvox Type of green algae
freshwater – ponds, ditches, puddles, lagoons
Colonies use flagella to swim
Cells have eyespots
Reproduces asexually and sexually
Autotrophic
Makes food by photosynthesis
