Protozoans

If you wanted to find a colony of protists, where might you look?

• Forest
• Desert
• Mountain
• Pond

What do all protists have in common?

• Their cells have nuclei
• They can make their own food through photosynthesis
• They live in saltwater environments
• They are multicellular

Which term best describes algae?

• Predatory
• Consumer
• Plant-like
• Prokaryotic

What might happen if a protist was missing its flagellum?

• It wouldn't be able to digest food
• It wouldn't be able to move
• It wouldn't be able to reproduce
• It wouldn't be able to breathe

Where might a parasitic protozoan live?

• On the ocean floor
• Inside a pig's intestines
• On the surface of a pond
• In the mud of a riverbank

Which of the following is an example of a fungus-like protist?

• algae
• amoeba
• slime mold
• flagellate

Downy mildew and water mold can both be classified as:

• Parasites
• Protozoans
• Psuedopods
• Plant-like protists

The main functions of the vacuoles found inside protozoans are:

• Digestion and excretion
• Locomotion and respiration
• Reproduction and cell division
• Photosynthesis and metabolism

What can you infer about protozoans from the fact they are single-celled organisms?

• They are probably unable to make humans sick
• They probably have no DNA in their cells
• They are probably poorly adapted to their environments
• They probably can't be seen without a microscope

How does an amoeba move?

• It uses cilia
• It uses flagellum
• It uses pseudopods
• It cannot move
