meristems?

b) a seasonal change in leaf morphology
c) a rapid change from a vegetative state to a
reproductive state

e) production of a fixed number of segments
during growth

2. One important difference between the anatomy of
roots and the anatomy of leaves is that

xylem.
b) the cells of roots have cell walls that are lacking in
leaf cells.
c) a waxy cuticle covers leaves but is absent in roots.
d) vascular tissue is found in roots but is absent from
leaves.
e) leaves have epidermal tissue but roots do not.

4. While studying the plant Arabidopsis, a botanist finds
that an RNA probe produces colored spots in the
sepals of the plant. From this information, which
information can be inferred?
a) The differently colored plants will attract different
pollinating insects.
b) The RNA probe is transported only to certain tissues.
c) The colored regions were caused by mutations that
took place in the sepals.
d) The RNA probe is specific to a gene active in sepals.
e) More research needs to be done on the sepals of
Arabidopsis.

5. Which of these statements about human evolution is
true?
a) The ancestors of Homo sapiens were chimpanzees
and other apes.
b) Human evolution has proceeded in an orderly fashion
from an ancestral anthropoid to Homo sapiens.
c) The evolution of upright posture and enlarged brain
occurred simultaneously.
d) Different features have evolved at different rates.
e) Mitochondrial DNA analysis indicates that modern
humans are genetically very similar to Neanderthals.
