Biology Kingdoms

Third Part of Student Download

KEY CONCEPT Kingdom Protista is the most diverse of all the kingdoms. Some scientists propose to break Protista into several kingdoms because they are very diverse & do not fit into other kingdoms.

Didinium, the brown organism, is a specialized protist that eats only paramecium.

• eukaryotes that are NOT animals, plants, or fungi.

Protista

Another view of Didinium

–heterotrophs –single-celled

Protozoa: Animal-like protistaClassified by method of movement

Protists can be animal-like, plantlike, or funguslike.

Oxytricha, an example of an animal like protist.

Slime Molds: Funguslike protista– decompose dead organisms.– heterotrophs – can move, whereas fungi cannot

Fuligo septica is also known as dog-vomit slime mold.

Protozoa: Animal-like protistaClassified by method of movement

• Sarcodina• Ciliaphora• Zoomastigina• Sporozoa

Phylum Rhizopoda: use pseudopoda

Amoeba

Phylum Foraminifera: also use pseudopoda

Foraminifera

Phylum Foraminifera

Radiolaria

Phylum Ciliaphora: use cilia to move

Paramecium:Move by cilia

More Paramecium

Zoomastigina (animal-like use flagella)

Leishmania

Phylum Zoomastigophora: use flagella(called Zooflagellates)

Trypanasoma: causes African Sleeping Sickness

Plasmodium: a parasitic protist that causes malaria

Apicomplexa Phylum (Sporozoa): no movement

Sporozoa: no movement

Toxoplasma

Other Zoomastigina

Giardia

• Algae: Plantlike protista– photosynthetic– single-celled or multicellular– no roots, stems, or leaves

Pediastrum is algae that lives in colonies and use sunlight to make food.

Algae: Plant-like Protista

• Chlorophyta (green algae)• Rhodophyta (red algae)• Chrysophyta (golden brown algae)

• Pyrrophyta (fire algae)• Euglenophyta

Algae Phyla:Phylum Chlorophyta (green algae)

Spyrogyra: a form of green algae normally found in freshwater

More Phylum Chlorophyta

Volvox: also a type of green algae

Phylum Rhodophyta (red algae)

Phylum Bacillariophyta (golden brown algae,) Chrysophyta)

Diatoms

Phylum Dinoflagellata (fire algae, Pyrrophyta )

Dinoflagellates

Phylum Euglenophyta

Euglena: move by flagella
