the correct answer.
A. (T or F) Charles Darwin's "The Origin of Species" had very little
influence on later works on Plant Taxonomy.
B. (T or F) The first system of classification that organized
flowering plants based on evolutionary relationships was done by George
Bentham.
C. (T or F) Linneaeus' main contributions to Plant Taxonomy were a
referable system of classification and binomial nomenclature.
D. (T or F) Possession of a copy of Dioscorides major botanical work
insured the owner a successful career as an agriculturalist during the
Middle Ages.
E. (T or F) There was a considerable amount of original work done on
Plant Taxonomy during the Middle Ages.
F. (T or F) A major impetus to develop better systems of plant
classification was the large number of new plants coming back from the
voyages of discovery in the Renaissance.
G. (T or F) Preliterate humans probably had very little knowledge of
their local flora and fauna.
H. (T or F) Theophrastus was apparently the first to recognize various
types of sexual and nonsexual reproduction and the distinction between
flowering and nonflowering plants.
I. (T or F) The two largest families of flowering plants are the Asteraceae
and the Poaceae.
J. (T or F) Most of grain production in the U.S. and Europe is directly
consumed by humans.
K. (T or F) The Fabaceae is the most economically family of flowering plants.
L. (T or F) Pratical classification systems have always reflected
evolutionary relationships.
M. (T or F) Angiosperm evolution and the composition of floras are closely
tied in with continental movements.
16. (5) (Circle ALL the correct answers) The Liliaceae and Iridaceae are
similar in that they both are herbaceous perennials that grow from (rhizomes,
corms, bulbs, woody bases, aerial roots, tap roots) but they are different
in that the leaves in the Liliaceae are (dissected, alternate, equitant) and
leaves in the Iridaceae are (entire, opposite, equitant).
17. (9) Which families (scientific names) are the following
economically important plants members of?
Family
Watermelon
Rice
Garlic
Water chestnut
Corn
Coconuts
Onions
Bamboo
Pineapple
18. (3) You have been sentenced for life to a deserted island by PTTS for
parking in a reserved-numbered slot but they are kind-hearted and have
provided shelter and all other means to exist except for food. There are
no edible plants on the island and you don't know how to fish or hunt, so
you will have to grow all your own food. You can choose seeds from two
angiosperm families to grow plants for your food. Which two families
would you choose and Why?
19. (2) Write a floral formula for the following flower:
Four sepals fused below, four petals zygomorphic and fused, 4 stamens
fused below to corolla, inferior ovary with 4 fused carpels.
