Classification of Organisms

Classification of Organisms

Procedure

  1. Select the first organism from Table 4 (E. coli).
  2. Using the “tree” (Figure 4; located at the end of this procedure) start at the top, and answer each question until the organism reaches the end of a “branch”. Write the organism’s name in the red box.
  3. Repeat this for the remaining organisms.
  4. After classification, fill in Table 4 with the correct domain and kingdom (when applicable) for each organism.

Post-Lab Questions

 

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

 

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

 

 

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