Protists
• Over 38,000 species of protists! • Members of the original life forms on earth!
About 1.5 billion years ago! • Some protists are plant like, some are animal
like – Protozoa: animal like protists
• Many have symbiotic relationships: – Parasitism
• Scientists who study only protists: protozoologists
Protozoa
• Protozoa – Unicellular, plasmic organization – BUT THAT DOES NOT MEAN THEY ARE
SIMPLE – Individuals or colonies
Describe the characteristics of the species:
Actinospharium
Difficult?
• What if you used taxonomy? – Domain: Eukarya – Kingdom: Protista – Phylum: Sarcomastifophora – Class: zoomastigophorea– Subphylum: Pseudopodia
• TAXONOMY GIVES US CLUES! • USE IT!
Phylum Sarcomastigophors
• Largest protozoan phylum. • All protozoa in this phylum:
– Unicellular or colonial – Locomotion by flagella, pseudopodia, or
both – Autotrophic, saprozoic, heterotrophic – Single type of nucleus – Sexual or asexual reproduction
Euglena
• Class Phytomastigophorea – Possess chlorophyll, 1 or 2 flagella
Euglena
• Salt or fresh water • Can perform
photosynthesis or absorb nutrients – The stigma at the base
of the flagella allows the euglena to orient themselves towards a light source
• Reproduce using binary fission– Split into two new
organisms
