Classification of Protists

Primarily classified by how they obtain nutrition (eat)

Three types:

Animal like (heterotrophs) Plant-like (autotrophs) Fungus-like (heterotrophs)

Multiple Choice

• Creates its own energy through photosynthesis

• Has fur

• Eats other living things

• May be green

Multiple Choice

• Creates its own energy through photosynthesis

• Has fur

• Eats other living things

Methods of Movement

Three main types of locomation:

Flagella -- whip-like "tail" Cilia -- tiny hairs along the cell Psuedopod -- cell pours cytoplasm into "false foot" to move

Flagella

Notice the long "tail" connected to the cell. These are the flagella.

Notice the lack of cilia and flagellum. The extensions from the cell are the psuedopods.
