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

Heterotrophic Didinium 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.
