A houseplant is growing on your windowsill. Every Sunday,
without fail, your roommate turns the plant 180 degrees. When
you ask your roommate why she does that, her reply is simply, "I
want straight plants." Does this method produce straight plants?
A. No. The statoliths in the plant cells do not respond to turning;
the plant will grow straight whether or not your roommate turns
the plant
B. No. The auxins don't respond to turning, only to light
C. Yes. Rotating the plant will even out the growth of the plant
toward the light by changing where the light hits the plant every
week
D. Yes. Rotating the plant redistributes the statoliths, so they
remain in the bottom of each cell - ANSWER-C. Yes. Rotating the
plant will even out the growth of the plant toward the light by
changing where the light hits the plant every week

The formation of branches in a root allow the root to maximize
surface area for the absorption of water and nutrients. How is it
that new branches ,ay begin transporting resources to the plant
almost as soon as the branch is formed?
A. The new branch forms from the cortex, which is in contact with
the pericycle of the root
B. The new branch forms from the cortex, which is in contact with
the vascular cylinder of the root
C. The new branch from the pericycle, which is in contact with the
vascular cylinder of the root
D. The new branch forms from the pericycle, which is in contact
with the central cortex of the root - ANSWER-C. The new branch
from the pericycle, which is in contact with the vascular cylinder of
the root

What is the role of the PEP carboxylase enzyme during both CAM
and C4 photosynthesis?
A. to capture CO2 in the form of HCO3
B. to capture CO2 in the form of 4-carbon organic acids
C. to capture CO2 in the form of 3-carbon organic acids
to create ATP - ANSWER-B. to capture CO2 in the form of 4-
carbon organic acids
How do the two species that make up a lichen benefit from their
symbiotic association?
A. The fungi receive carbohydrates from the algae, while the
algae receive water from the fungi
, 4|Page
B. Both partners can control the timing of reproduction of the
other partner
C. The algae receive carbon as a result of the fungi's ability to
degrade lignin and cellulose, while the fungi receive nitrogen from
the algae
D. The fungi receive carbohydrates from the algae and the algae
functions in anchoring the lichen on the substrate
E. The fungi receive water from the algae, while the algae receive
carbohydrates and nitrogen from this fungi
F. Both partners are able to suppress reproduction in each other
The fungi receive carbohydrates and, in some cases, nitrogen
from the algae, while the algae gain a "home" that anchors them
on the substrate - ANSWER-A. The fungi receive carbohydrates
from the algae, while the algae receive water from the fungi
F. The fungi receive carbohydrates and, in some cases, nitrogen
from the algae, while the algae gain a "home" that anchors them
on the substrate
