1. Objective 1.1 Compare the structures and life functions of single-celled organisms that carry out all of the basic functions of life including:
SWBAT define and explain the following terms:
Organism, Euglena, Paramecium, function, Amoeba, Volvox
SWBAT describe and compare the structures and functions of single celled organisms.

2. Essential Question: What are the characteristics of the following single-celled organisms? Amoeba Euglena Paramecium Volvox

3. What do the following single celled organisms have in common?
AMOEBA
PARAMECIUM
EUGLENA
VOLVOX

4. Comparisons of Single-celled Organisms
Please write down anything that is in RED in your own words. These are the important concepts.

5. Amoeba Move by cytoplasmic streaming
Surrounds food and engulfs it using pseudopods, it is then enveloped, stored, and digested in vacuoles

6. Amoeba Can change shape Heterotrophic
Eukaryotic – contain one or more nuclei
Eats bacteria, algae, and other protozoa
Reproduce asexually
Can become dormant
Can survive forcible division

7. Euglena Move by flagellum Known for a unique feature—eye spot
Contain chloroplasts
Common in fresh water
Do not contain a cell wall

8. Euglena Found in calm fresh and Used as a model organism in the lab
salt water
Used as a model organism in the lab
Autotrophs – get energy via photosynthesis
Can also get nourishment heterotrophically like animals
Have features of both plants and animals > Kingdom Protista

9. Euglena Heterotrophic feeding
surrounds particle of food and absorbs it
Autotrophic feeding produces sugars via photosynthesis where sufficient sunlight is present
Does not contain a cell wall
Moves by use of a flagella

10. Paramecium Most complex and specialized of the protists
Moves by cilia (hairlike projections)

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

12. Paramecium Uses cilia to sweep food into the oral groove
Feeds on micro-organisms like bacteria, algae, and yeasts
Stiff elastic membrane gives it shape and is covered in cilia that allow it to spiral through water

13. Volvox A sphereical colony of ciliates may include up to 50,000 cells
Contain chloroplasts
Move and act as one multi-cellular organism
Can survive independent of the colony

14. Volvox Type of green algae
Lives in lots of freshwater habitats – ponds, ditches, puddles, lagoons
Colonies use flagella to swim
Cells have eyespots
Make food via photosynthesis
Autotrophic
