D. ATP is produced by the light reactions.
C
Answer
What is the independent variable in this
experiment?
Answer
The amount of CO2
Possible answers:
What is a possible dependent variable for this · Plant growth
experiment (There is more than one answer)? · Plant mass
· Amount of Starch/glucose produced
· Amount of oxygen produced
· other possible answers?
What is an appropriate control for this experiment?
Set up a plant that is not under a bell jar. Or set up a
plant in a bell jar where air can freely enter and leave
the environment.
Plant A is placed in direct sunlight for two days. After two
days the leaves are tested for their starch content. How would
the starch content of this plant compare to a plant grown under
normal conditions?
Plant A would produce little to no starch since there is no CO2 available. The
plant grown under normal conditions would have starch in its leaves.
Plant B is placed in direct sunlight for two days. After two days
the leaves are tested for their starch content. How would the
starch content of this plant compare to a plant grown under
normal conditions?
Since plant B is being supplied with CO it would contain just
2
as much starch as a plant grown under normal conditions.
What can be concluded by the data?
More bubbles are produced when the plant is closer to
the light source.
What gas do the air bubbles contain?
O (oxygen)
