PROTISTS

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

REPRODUCTION

Asexual

Mitosis and cytokinesis

Budding

Sexual

Meiosis

Conjugation

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
