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

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.
