charged is
a) photobleaching
b) photoionization
c) photorespiration
d) resonance
e) none of these is correct - Correct Answers -b) photoionization
The dark reactions of photosynthesis require?
a) ATP
b) NADPH
c) CO2

Measurements of the amount of DNA per nucleus were taken on a large number of cells
from a growing fungus. The measured DNA levels ranged from 5 to 10 picograms per
nucleus. It is most likely that a cell which contained 5 picograms of DNA was in the
following stage of the cell cycle
a) G1
b) G2
c) M
d) none of these is correct - Correct Answers -a) G1
One way photosynthesis in a typical C4 plant differs from that in a C3 plant, is that the
C4 plants
a) C4 does not produce any oxygen gas at all
b) C4 actively pumps oxygen gas away from the cells that contain rubisco
c) C4 avoids the use of rubisco entirely; instead, it uses only PEP carboxylase to
catalyze carbon fixation
d) C4 keeps its stomata more open, so that more CO2 can enter the plant
