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

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
