PROTISTS
COMMON EXAMPLES: Amoeba, paramecium, euglena, volvox, plasmodium
EUKARYOTIC
Have a nuclear membrane
VERY DIVERSE GROUP
most are unicellular, microscopic, aerobic
Some are autotrophic, heterotrophic, sexual, asexual
PROTISTS
EXCRETION AND
OSMOREGULATION
Water balance = osmoregulation
Done by contractile vacuole
Wastes removed by diffusion
RESPIRATION
Carbon dioxide and oxygen diffuse in
and out
PROTISTS
DOMAIN
EUKARYOTA
KINGDOM PROTISTA
Any eukaryote that is
not classified as a
fungus, plant, or
animal is a PROTIST
PROTISTS
ANIMAL LIKE PROTISTS =
PROTOZOA
Classified by method of movement
PLANT LIKE PROTISTS = ALGAE
Classified by pigment color
FUNGUS LIKE PROTISTS = MOLDS
Classified by body form
PROTISTS
PROTIST CLASSFICATION
Separated by feeding habits (nutrition)
Autotrophic
Able to make own food
Photosynthetic – 30-40% of all photosynthesis
worldwide is done by algae
Heterotrophic
Must eat other material
Unicellular
May be predators, decomposers, or parasites
