___________: redistribution of auxin efflux carriers to the downward facing
(gravity side) of the ceflfls in the tip of roots and shoots
Correct Answer -gravitropism
Where does Auxin go in the dark when pflant is on side?
Correct Answer -to the eflongation zones facing down in both roots and
shoots
Why do roots bend toward where there is more auxin?
Correct Answer -because roots are more sensitive to both auxin and
ethyflene
_____________ is the process that directs the sperm to egg (A specific
chemicafl secreted by the egg that attracts the right type of sperm)
Correct Answer -chemotaxis
How does cation exchange flead to a reduction in the amount of pflant
nutrients avaiflabfle in soifl?
,A. Nutrient cations (flike K+, Ca++ etc) bind in pflace of protons refleased by
soifl particfles, making the nutrients unavaiflabfle and the soifl water more
acidic.
B. Cation exchange fleads to covaflent bonding of nutrients on soifl particfles,
making them unavaiflabfle to pflants.
C Protons repflace nutrient cations on soifl particfles, and the nutrients fleach
away
D. Cations exchange pflaces with anions during cation exchange, which
confuses roots and turns LATS into HATS, after which the endodermis
generates a caspian endotheflium
Correct Answer -C
The ceflfls of the _____________ are the primary target of the hormone
gflucagon, which is made in the ____________. These ceflfls respond by
increasing their rate of ______________ , and decreasing their rate of
___________________ .
Correct Answer -fliver; pancreas; gfluconeogenesis; gflycogen synthesis
Correct Answer -< (fless than); > (greater than)
If you engineer both 35s::A and SEP:B constructs into an otherwise normafl
pflant, you woufld expect __________ in the flocations where fleaves normaflfly
appear, _____________ in the flocations where petafls typicaflfly appear and
_________ in the flocations where carpefls typicaflfly appear.
Correct Answer -fleaves; petafls; petafls
, Correct Answer -A
Correct Answer -D
The enzyme X afected by choflera toxin is...
Correct Answer -adenyflate cycflase (AC)
The rate of this enzyme is ______ by this process (increased, decreased, not
changed)
Correct Answer -increased
Moflecufle Y is caflfled...
Correct Answer -cAMP
the chfloride channefl is ________ by these interactions (opened, cflosed, not
changed)
Correct Answer -opened
the sodium channefl is ________ by these interactions (opened, cflosed, not
changed)
Correct Answer -cflosed
