PROTISTA
Kingdom,
Phylum
Example
Domain
Eukarya
Autotrophic by
photosynthesis, some
heterotrophic by
phagocytosis, or both
All:
Kingdom
Protista
Animal-like
Protists
Phylum
Protozoa
Nutrition & Digestion
Heterotrophic
(phagocytosis – engulf
food)
Reproduction & Cell Type
Importance
Mostly unicellular;
multicellular forms: lack
tissue organization
Cell type: eukaryotic;
have nucleus and complex
organelles
Classified based on what they
don’t have.
Many different types of
movement based on
structure of species
Reproduction: Asexually
(binary fission or multiple
fission), sexually
(conjugation)
Move independently with
pseudopodia (cytoplasmic
extensions)
Unicellular
cilia
Unicellular
Flagella
Binary fission and sexual
reproduction
(conjugation-2 cells join
and their macronuclei
disintegrate. Meiosis, then
mitosis- see text)
Unicellular
Believed to be the first cells
that developed into the more
complex cells of organisms in
the animal kingdom.
Binary fission
Amoebas
Some parasitic

Digestion: oral groove,
mouth pore, gullet, anal
pore, contractile vacuole

Heterotrophic and
autotrophic
