1. The process called _______ refers to the type of speci- cladogenesis
ation in which branching of several new species from
an ancestral lineage occurs.
2. the word that is the antonym of 'extant': extinct
3. plant sporophytes produce ________ by __________. spores; meiosis
4. in flowering plants, meiosis occurs specifically in: microspore mother cells
5. the gametophyte depends upon the sporophyte for conifers
nutrition and protection in which group or groups?
6. organisms that use light to generate ATP, but must photoheterotrophs
ingest organic molecules for their carbon needs, are:
7. a microspore divides once by mitosis and produces generative cell
a(n) ___________ and a tube cell, which make up the
immature male gametophyte in angiosperms.
8. which of the following mechanisms is NOT used in meiosis
prokaryotes?
9. if coyotes and panda bears are in the same class, then phylum
they must also be in the same:
10. the water molds are in the protistan group: Oomycota

12. the protistan group that possess a large amoeboid slime molds
mass (called the plasmodium) at some time in the life
cycle:
13. swifts and swallows are aerial foragers, although the must have resulted from
two birds are similar in appearance, biologists place convergent evolution
them in different orders, genetic analyses show that
swifts and swallows are not closely related. Therefore,
their similarities:
14. You are an exobiologist aboard the starship Beagle. transduction
You observe a process where alien viruses transfer
genes from one alien bacterial cell to another. You call
your freshman biology professor and tell him that you
have observed ________ in alien bacterial species.
15. the pine trees are in the division: coniferophyta
16. convergent evolution: (EXPLAIN) means that two or more
species begin to appear
more alike, due to similar
responses to the environ-
ment
17. A friend gave you a plant to identify. It has the fol- moss
lowing characteristics: no vascular tissue, no cuticle,

sporophyte growing out of the gametophyte, flagel-
lated sperm. You determine it is a:
18. the outermost modified leaves of a flower are the: sepals
19. which of the following two types of bacteria that are gram-positive bacteria
considered to be less dangerous (pathogenic) than
the other:
20. mitochondria and chloroplasts are found in both false
prokaryotes and eukaryotes: (TRUE/FALSE)
21. A visiting scientist from another planet is interested in phylogenetic
the taxonomy of life on Earth. The visitor examines the
anatomy of coyotes, wolves, German shepherds and
toy poodles. The visitor notes that shepherds and poo-
dles interbreed most readily, but notes that wolves
also can interbreed with poodles, shepherds, and coy-
otes, and coyotes with the poodles and shepherds.
However, DNA analysis and amino acid sequences
both show that there are greater similarities between
the shepherd and the poodle than either dog has with
wolves or coyotes. The visitor concludes that there are
three distinct evolutionary groups with a single com-
mon ancestor (the dogs, coyotes, and wolves form a
monophyletic group), but each species has its own
history and its own evolutionary fate. The visitor is
using the _____ species concept for determining which
organisms are of the same species.
22. Ferns are more 'advanced' than mosses because xylem
mosses generally lack which structure that is found in
ferns?
