Protist Lab
Name ____________________
Procedure:
Using the microscope, find each organism in low power, then in high power.
A. Make an accurate drawing of each organism in HIGH POWER.
(this MUST be done IN CLASS
B. Label the parts on the drawing listed next to the organism’s name.
C. Next to each label write a short, three or four word definition for that cell part.
D. Answer the questions that follow.
Paramecium (Yours 215, Froggy 236) Draw in the space below. Label: cell
membrane, cilia, contractile vacuole, oral groove, food vacuole, micronucleus,
macronucleus, anal pore. Don’t forget a short (4-5 word) definition (job).
1. Explain how a Paramecium eats.
2. What are cilia?
3. What is the function of the contractile vacuole?
Euglena (Your 212, Froggy 231) Draw in the space below. Label: eyespot, flagellum,
chloroplast, cell membrane, nucleus. Don’t forget a short (4-5 word) definition (job).
4. What two ways do Euglenas eat?
a.
b.
5. In the Euglena, what is the purpose of the red eyespot?
6. Why would a Euglena swim toward the light?
Amoeba (Yours 216, Froggy 234) Draw in the space below. Label: pseudopod, cell
membrane, cytoplasm, nucleus, food vacuole. Don’t forget a short (4-5 word) definition
(job).
7. How does the shape of the Amoeba compare to the shapes of the Paramecium
and the Euglena?
8. What does the word prefix “pseudo” mean?
9. What does the word suffix “pod” mean?
10. What two things does an Amoeba use pseudopods to do?
a.
b.
Analysis Questions
11. Circle the protist group(s) each organism belongs to:
Euglena
=
plant-like,
animal-like
or fungus- like
Paramecium
=
plant-like,
animal-like
or fungus- like
Amoeba
=
plant-like,
animal-like
or
fungus- like
12. What structures are responsible for the way each of these protists move. (List the
form of movement for each organism)
Euglena
=
Paramecium
=
Amoeba
=
13. Why do some protists need to be able to move?
