Kingdom Protista

The most diverse kingdom

Protist• The protist

kingdom contains the most diverse collection of organisms.

Protist• The one

characteristics all protist share is that they are all eukaryotes.

• Their cells have a nucleus and membrane bound organelles.

• List 5 organelles.

Protist• Protists can be

classified into 3 groups.

• Animal-like: they are heterotrophs

• Plant-like: they are autotrophic

• Fungus-like: they are decomposers

Protozoa• Animal-like protists

are call protozoa• All are unicellular• All are heterotrophs• All are aquatic• Reproduce asexually• Protozoa:

Enoploplastron triloricatum

Protozoa• Classified by they

way they move• Cilliates: protozoa

covered by hairlike structures

• Paramecium

HeterotrophicDidinium eating a

Paramecium•

Protozoa• Flagellates- use

whiplike flagella to move

Protozoa• Amoeba- move by

sending out pseudopodia (false feet) and oozing around

Protozoa• Sporazoans-

produce spores• All are parasites• Plasmodium lives

in mosquitos and causes malaria

Algae• Plant-like protist

are called algae• Both unicellular

and multicellular• All are autotrophs

Algae• Algae can be

classified into six groups

• The euglenoids, diatoms and dinoflagellates are all unicellular

Algae• The multicellular

algae can be classified as green, red, or brown

Spyra Gyra•

Kelp•

Dynoflagellate•

Euglena with red eyspot•

Molds and Mildews• Fungus-like

protists are the water molds, downy molds and slime molds

Mold and Mildews• All molds and

mildews are decomposers

Mold and Mildews• Slime molds have

the characteristics of both protozoans and fungus-like protists.

• During part of their life cycle they are mobile.
