Protista Lab
Purpose: To identify the most common tpes of Protozoans. To have a better understanding of
their cell structures, shape, and methods of locomotion.
Background:
1. What are the 3 major kinds of Protists?
____________________________________________________________________________________
2. What is the major characterisitic that differs between organisms in each of the 3 groups?
____________________________________________________________________________________
Materials: Prepared slides of : Amoeba, Paramecium, and Euglena, microscope, & Virtual Labs for
Euglena, Paramecium, and Amoeba http://labs.7bscience.com/protist-labs.html
Procedures: Part 1: Prepared slide of Amoeba
1. Obtain a prepared slide of Amoeba
proteus.
2. Find the pink or blue-stained Amoebas
on the slide and focus on high 40x
power.
3. Draw an Amoebas on your slide. On
each drawing label the following parts:
Plasmalemma, nucleus, pseudopod,
and magnification.
** If the Amoeba that you are looking at
doesn’t have a definite pseudopod, then
DO NOT draw it.
PART 2. Prepared slide of Paramecium
1. Obtain a prepared slide of Paramecium
caudatum..
2. Find the stained paramecium on the
slide and focus on high 40x power.
3. Draw a paramecium on your slide. On
each drawing label the following parts:
Pellicle, macronucleus, cilia &
magnification.

PART 3: Prepared slide of Euglena
1. Obtain a prepared slide of Euglena
2. Find the purple stained Euglenas on the
slide and focus on high power 40x
3. Draw the Euglena on your slide. On each
drawing label the following: Pellicle,
chloroplast & magnificaiton
PART 4: Volvox (colony of flagellates)
1. See Volvox See Handout (attached and Pictures of magnified Volvox on the front screen.
Data and Results
1.Describe how an Amoeba moves. _______________________________________________________
__________________________________________________________________________________
2.What do we call the projections that the Amoeba uses for movement? __________________________
3.What is the body symmetry of an Amoeba? ______________________________________________
4.How does a Paramecium move? ________________________________________________________
5.How would the Paramecium get a yeast cell into its body if it wanted to eat it? Explain in detail.

7.What structure does an Euglena contain that make it more “plant-like”? _____________________
8.Why would a Volvox, which is a colony of single celled flagellates, be a beneficial way of living?
