(Note: There is no answer key. All of this material is drawn directly from
your lab exercises, lab manual or textbook so you should be able to go back
and find the answers there. Get in touch with your lab instructor if you need
help to sort things out)
We have attempted to cover the most important points here. This list may
not be exhaustive. Remember, if the material is in your lab manual or your
lab manual refers to pages in your text, it is fair game for the lab exam.
STUDY HARD. The quiz is not easy.
SPELLING will count. You will only get full marks if you have spelled
something correctly.
TAXONOMY and the TREE of LIFE
1. Know the basic terms for plant morphology (p. 112). Be able to recognize
alternate vs. opposite leaf arrangement, and to recognize the attachment of leaves
to conifer branches. These are all terms you would have encountered for the I-
Naturalist project.
2. Know the difference between a stereomicroscope and a compound light
microscope and for what purpose you might use one rather than the other (shown
in appendix I).
3. Be familiar with scientific drawing guidelines, including the format of a figure
caption and how to do a calculation of a drawing magnification.
4. Know basic terminology for specimen preparation such as cross-section vs.
longitudinal sections vs. whole mounts vs. wet mounts.
5. Recognize the three facets of taxonomy: classification, nomenclature,
identification and the meaning of each of those aspects.
6. Know the hierarchical levels – from most inclusive to least inclusive. Be able to
recognize the hierarchical levels of taxonomic names shown on the branches in
Fig. 1-2 on p. 7 (for example, Plantae, Animalia, Fungi are Kingdoms and
Arthropoda & Chordata are Phyla, etc.)
7. Know how to identify a common ancestor on a phylogenetic tree and how to
determine a node that shows divergence of select taxa.
8. Know how to write a latin binomial (format).
9. Know the basic rules for building a dichotomous key – and how to use one for
keying out a specimen.
NATURAL SELECTION and ADAPTIVE EVOLUTION
1. Be sure you can define micro-evolution and compare it with macro-evolution. Be
sure you know the bold faced terms in the introduction and can use them in a
meaningful discussion.
2. Review the lab objectives on p. 12 & 13 and be sure you are comfortable with all
points.
