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
