Protists
  • Animal-like vs Plant or Fungus like..
  • Called Protozoans
  • Divided into 4 groups
  • Pseudopods
  • False Feet.
  • Move by bulging cell membrane and flowing
    cytoplasm.

Protists
  • Animal-like vs Plant or Fungus like..
  • Called Protozoans
  • Divided into 4 groups
  • Ciliates
  • Have cilia
  • Hair like projections used for moving, sensing
    and obtaining food

Protists
  • Animal-like vs Plant or Fungus like..
  • Called Protozoans
  • Divided into 4 groups
  • Sporozoans
  • Parasites that feed on the cells and fluids of
    host.

Protists
  • Fungus-like vs Plant or Animal-like
  • Use spores to reproduce
  • Tiny cell able to grow into a new organism.
  • All able to move at some point in their lives.
  • Water Molds and Downy Mildew

Protists
  • Plant-like vs Fungus-like or Animal-like
  • Commonly called algae.
  • All are autotrophs.
  • Several Types
  • Euglenoids
  • Can be heterotrophic in no-light
