Visit the the PondScum Video Gallery to see AWESOME videos of microorganisms. When you visit the site, look for these Protozoans and Algae videos:
 

Protozoans

Algae

  • Euglena #2
  • Amoeba #2
  • Paramecium #6, #8
  • Stentor #8
  • Oscillatoria #1
  • Spyrolina #1
 

Have you ever looked at pond water under a microscope? If so, you have probably seen many different types of microorganisms. One common group of microorganisms is called protists. The table below shows information about four common types of protists.

Using the information in the table, illustrate a completed example of each organism. When your illustrations are completed, compare them to actual pictures of each organism by pressing the links in the last row of the table.

 

Paramecium

Euglena

Amoeba

Spirogyra (Algae)

Animal-like/plant-like

A paramecium is animal-like because it moves and searches for its own food.

They have characteristics of both plant and animal. Sometimes they make food and sometimes they don’t.

An amoeba is animal-like because of its ability to move. It searches for its own food.

A spirogyra is plant-like because of the presence of chlorophyll which allows it to make its own food.

Shape

Elongated oval-shaped body  Narrow oval-shaped body

Irregular shaped body

Tubelike body

Movement

Tiny hair like structures surrounding the body called cilia

One long and short tail-like structure called flagella

They push and pull with their pseudopods or false feet.

Free floating

Consumer/Producer

They find their own food.

Consumer

They can produce food through photosynthesis or consume food.

Either Consumer or Producer

They engulf food by surrounding it and pulling it in by the use of their pseudopodia.

Consumer

They produce their own food through the process of photosynthesis.

Producer

Color

Pale translucent color

Green because of chlorophll.

Pale translucent color

Green because of chlorophyll

Visit Pioneer Library and search e-Media for the video "The World of Fungi."
 

Extension:

  • Explain how the different types of appendages help protists move.
  • Explain the function of the green color found in some protists.
