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.

• Ciliates
– Have cilia
– Hair like projections used for moving, sensing and
obtaining food

Called Protozoans
Divided into 4 groups
• Sporozoans
– Parasites that feed on the cells and fluids of host.
Sporozoans
Plasmodium falciparum in blood, causes malaria

Trypanosoma in blood
causes sleeping sickness

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
