Plant and Animal Biology – Study Guide
Plant diversity and evolution (I)
General principles of biological classification (chapter 16)
List the seven levels of classification in order from general to specific:
How are problems addressed when a group seems to fit “between” categories?
Compare and contrast taxonomy and systematics
Describe the science of cladistics. What is a cladogram?
Explain what is meant by a primitive character state and a derived character state:
Species A and B are more closely related to each other than either is to C, D, E, or F. Species C
and D share a common ancestor not shared by the other 4. E and F also share a common ancestor
not shared by the other 4. C, D, E, and F share a common ancestor separate from A and B.
Draw a cladogram for these 6 species:
II) General features of the plant kingdom (chapter 20):
Major pigments:
Food storage product:
Cell wall material:
The ______ ______ forms during cell division.
The above are shared by _______ _______, indicating common ancestry with the plant kingdom.
Plants also have the following derived characteristics (adaptations to life on land):
Fatty (wax) cuticle:
Multicellular, dependent embryos:
III) Plant life cycle:
Alternation of generations (p. 227-8): this is important; so to be sure you get it draw a cycle diagram
with labels AND describe the process in words:
