Biology 102 Study Guide for the First Midterm Exam
Reread the first page of the syllabus for what
we are trying to accomplish in this course. "ST" below refers to
your text by Starr & Taggart
Specifically, here are the topics for which
you are responsible on the first midterm:
If you have any questions about what I am referring
to here, please bring them up in lecture or email me
Scales of Time and Space - The metric system of measurement (units of measure
and the general sizes of the organisms studied). Geological time as covered
in lecture (the names and starting times of the Eons).
Hierarchical classification system - basic idea of what the benefits of
using such a system are. You can learn common names or scientific
names or both for phyla. E.g. either Ciliophora or "ciliated protozoa"
is fine; "green algae" or Chlorophyta; "sponges" or Porifera; etc.
Defining characteristics of the six Kingdoms, plus additional general
characteristics as covered in lecture and ST for the EuBacteria, Archaebacteria,
Protista (this treated as a single kingdom, not like in ST), and Animalia.
Features used within these kingdoms to separate Phyla. In the Protista,
you are not yet responsible for the information on the Fungus-like Protista,
although you should be aware they exist. In the Animalia, you are
responsible for only the "early" invertebrates (sponges, cnidarians, flatworms,
roundworms and rotifers) covered before the exam.
The general "breakdown" of diversity within the "microbial" Kingdoms: Eubacteria,
Archaebacteria and Protista. You do not need to know all the phyla
covered in your text in these groups. Treat the material as covered
in lecture (i.e., the separation of the prokaryotes by means of chemical
structures & great diversity of metabolic capabilities, and the rather
arbitrary separation of the Protista into protozoa, algae and fungus-like
protista, based on their similarity to higher, multicellular Kingdoms).
Know details from the "troublesome microbe" handout of three such organisms,
at least one of which is a prokaryote.
Ecological/human importances of example organisms given in lecture OR in
What is nitrogen fixation, which organisms can do it and why is it important?
Evolutionary trends within and between the prokaryotes, Protista
and evolutionary connections of these Kingdoms to each other and the three
multicellular Kingdoms: Animalia, Plantae and Fungi.
Relative and approximate absolute timing of these major events: first
organism, first oxygen-releasing photosynthesis, first eukaryote, first
sex, first animal. You should understand what "forces" the organisms
may have been adapting to during each of these events.
