Experiment 2: Classification of Organisms

Materials Use Table 2 below as well as the "tree" (Figure 4; located at the end of this procedure)

Procedure

1. Select the first organism from Table 4 (E. coli).

2. Use the “tree” (Figure 4; located at the end of this procedure) start at the base, and answer each question until the organism reaches the end of a “branch”. Write the organisms name in the red box.

3. Repeat this for the remaining organisms.

4. After classification, fill in Table 2 with the correct kingdom for each organism.

Table 4: Key Characteristics of Some Organisms
Organism	Kingdom	Defined Nucleus	Mobile	Cell Wall	Photosynthesis	Unicellular
E. Coli				Yes		Yes
Protozoa		Yes	Yes	No		Yes
Mushroom		Yes		Yes
Sunflower		Yes	Yes	Yes	Yes
Bear		Yes	Yes

Post-Lab Questions

1. Did this series of questions correctly organize each organism? Why or why not?

2. What additional questions would you ask to further categorize the items within the kingdoms (Hint: think about other organisms in the kingdom and what makes them different than the examples used here)?

3. What questions would you have asked instead of the ones that you answered about when classifying the organisms?
