d)
chlorophyll
8.
Most plants appear green because chlorophyll
a)
absorbs green light.
b)
absorbs violet light.
c)
reflects green light.

12.
Use the diagram to answer the question. Between which parts of the molecule must the bonds be broken to form an ADP molecule?
a)
A and B
b)
A and C
c)
B and C
d)
C and D
13.
Use the diagram to answer the question. Which chemical is an electron carrier molecule?
a)
H2O
b)
carbon dioxide
c)
NADP+
d)
oxygen
14.
Plants need carbon dioxide from their environment to produce glucose during which stage of photosynthesis?
a)
The light-dependent stage
b)
The light-independent stage (The Calvin Cycle)
c)
The electron transport chain
d)
ATP formation
15.
Is ADP or ATP more like a fully charged battery, and why?
a)
ADP, because it has three phosphate groups; breaking and reforming the bonds among them releases energy.
b)
ATP, because it has three phosphate groups; breaking and reforming the bonds among them releases energy.
c)
ADP, because it has two phosphate groups; breaking and reforming the bonds among them releases energy.
d)
ATP, because it has two phosphate groups; breaking and reforming the bonds among them releases energy.
16.
Which of the following best describes photosynthesis?
a)
Photosynthesis converts radiant energy into chemical energy.
b)
Photosynthesis produces carbohydrates.
c)
Plants need sunlight, carbon dioxide, water, nutrients, and chlorophyll to complete photosynthesis.
d)
Plants use chlorophyll, water, and carbon dioxide to make sugar.
