Review Questions
1.
Accessory pigments include molecules that reflect the
red, orange, and yellow colors. Leaves of many plants
show these colors in the fall because
the chlorophyll a & b in the
leaves degrade as the cold
weather approaches.
2.
All of these organisms can carry out photosynthesis:
algae, cyanobacteria, and
plants.
3.
The Calvin cycle
is a cyclic reactive pathway
that produces three-carbon
molecules from CO2.
4.
Discrete packets of kinetic energy in light are called
photons
5.
The electrons flowing through the electron transport
chains in photosynthesis come
from ________ and end up being carried by
__________.
water; NADPH
6.
The energy source for the process of photosynthesis is
sunlight
7.
The energy sources needed for the light reactions and
Calvin cycle
carbon reactions, respectively are
sunlight and ATP.
8.
Examples of accessory pigments for photosynthesis
are
chlorophyll b and carotenoids
9.
A gelatinous fluid inside the chloroplast containing the
ribosomes, DNA,
and enzymes is the
stroma
10.
How do C4 plants minimize photorespiration?
The light reactions and carbon
reactions occur in different
cells,
so oxygen does not come into
contact with rubisco.
11.
How do CAM plants minimize photorespiration?
Stomata are only opened at
night, storing carbon dioxide in
malate.
During the day the carbon
dioxide is released for
photosynthesis.
12.
Identify the incorrect pairing of thr photosynthetic
carbon pathways and
the type of earth's habitat in which they live.
D. C3 pathway plants are found
in almost all earth's plant
biomes.
