1. Protists!
Clockwise: Volvox, Globigerina, Amoeba, Chlamydomonas, Trypanosoma, Euglena, Radiolarian, Stentor, Paramecium, Vorticella

3. General Characteristics
eukaryotic – cells contain membrane-bound nuclei and other membrane-bound organelles
can have unicellular, colonial and multicellular forms
important role at the bottom of the food chain
reproduce via binary fission
level of organization: protoplasmic
all functions of life are performed within
the limits of a single plasma membrane

4. Autotrophic v. Heterotrophic
autotrophic – converts inorganic compounds into an organic,
usable form through
photosynthetic processes
Ex. Volvox, Euglena
heterotrophic – ingest large food particles and digest them intracellularly
Ex. Amebas, Paramecium

5. Amoeba (Ameba)
