Comparing the Ameba to the Paramecium - Virtual Lab

Objective: In this lab, students were observing living ameba and paramecium. If specimens were not cooperating, you can alternatively view these specimens using images found at websites, photo sites, and videos. Both the ameba and the paramecium belong to the Kingdom Protista and are also sometimes called protozoa. Each specimen moves in a unique way. Your task is to analyze and compare the protozoan movements.

Describe in your own words how the ameba moves.


3. Draw the ameba. Label the: Endoplasm, Ectoplasm, Cell Membrane, Pseudopodia






4. While at youtube, find a video of the paramecium. There will be many. Your goal is to locate a paramecium as it is moving, feeding, or responding to objects in its environment.

5. Describe how the paramecium eats and digests food:


6. Draw a paramecium. Label: Nucleus, Oral Groove, Cell Membrane, Cilia, Contractile Vacuole







7. Compare the movement of the paramecium to the movement of the ameba.



8. How are the paramecium and the ameba alike?



9. How are the paramecium and the ameba different?



10. Compare the shape of the paramecium to the shape of the ameba.
