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)
Types of movements:
2. Sarcodine (Extension
of cytoplasm)
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:
Euglenophytes
Chrysophytes
Diatoms
Dinoflagellates
Plantlike protist that have
two flagella BUT NO
CELL WALL
Among the most abundant and beautiful
organisms
Half their life is photosynthetic;
the other half is heterotrophic
Heterotrophs that absorb
nutrients from dead or decaying
organic matter
Fungus-like protist include:
1.Slime molds
-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?
