What are protists?• Very diverse group of organisms
containing over 200,000 species• NOT members of the kingdoms
plantae, animalia, fungi or bacteria• Eukaryotes• Most are unicellular
How are protists classified?• According to the way they obtain
nutrition:– Autotrophs (plant-like)– Heterotrophs (animal-like)– Decomposers and parasites (fungus-like)
Animal like protists (protozoans) are
distinguished from each other by the
way they…
Types of movements:1.Zooflagellates (flagella)
2. Sarcodine (Extension of cytoplasm)
Types of movements:
Types of movements:3. Ciliates (cilia)
Animallike Protists: Sporozoans
• Parasitic to animals–Do not move on their own
Drill Partners• Turn to your neighbor and drill one
another on the four categories of animallike protists and how they move.
• Make certain you both know the four categories and can recall them from memory.
Protists that perform photosynthesis are grouped into a category called:
Commonly called…
Unicellular plantlike protists are:
EuglenophytesChrysophytes
DiatomsDinoflagellates
Plantlike protist that have two flagella BUT NO CELL WALL
Half their life is photosynthetic; the other half is heterotrophic
Heterotrophs that absorb nutrients from dead or decaying organic matter
-Thrive on dead or decaying organic matter in water
-Plant parasites on land
Ticket Out the Door
What characteristics do these organisms have that place them in the Kingdom Protista?
