BIOD 171 FINAL EXAM
1. True or False: A virus is considered a microorganism.
False. Viruses are not living and as such are not considered microorganisms. Viruses can,
however, be classified as microbes, a more general term that includes microorganisms and
viruses.
2. What is the smallest biological unit of life?
A cell.
3. At a generalized level, all cells are comprised of what?
Macromolecules*
*A student may also answer: Proteins, Lipids, Nucleic acids and Polysaccharides but they
must answer with all four to be fully correct.
1. Animalia, Plantae, Fungi and Protista are all classification under what type of
organism?
A. Bacteria
B. Eukarya
C. Archaea
D. Virus
B. Only Eukarya contains animals, plants, fungi and protists.
2. All multicellular microorganisms classified as Animalia are autotropic.
False—they are heterotropic.
3. Microorganisms classified as obtain most of their energy by converting light
energy into chemical energy.
Plantae

1. Assuming a constant (non-adjustable) light source power, identify the part of the
microscope you would adjust to limit the amount of light entering the microscope.
Select all that apply.
A. Objective
B. Condenser
C. Iris diaphragm
D. Eye piece
C. The iris controls the amount of light that passes through the sample and into the objective
lens. Thus, it can be adjusted (opened or closed) to alter the amount of light.
2. What is the total magnification (relative to your eye) of a sample imaged with a 60x
objective and a 10x eyepiece? Show your math.
60 x 10 = 600x magnification
1. Identify what type of electron microscope was used to capture the following image
and explain your choice.
