A student sets up an investigation by placing a plastic bag over a plant. She secures the plastic bag so that it is completely sealed and nothing can enter. She observes the plant daily to see if it remains green and healthy.
Which TWO questions is this investigation, as described, designed to answer?
a
Can the plant perform respiration without a large supply of oxygen?
b
Can the plant perform photosynthesis without a large supply of carbon dioxide?
c
Can the plant perform photosynthesis faster than a plant that is not sealed?
d
Can the plant perform photosynthesis without a large supply of oxygen?
e
Can the plant perform respiration without a large supply of carbon dioxide?
f
Can the plant perform respiration faster than a plant that is not sealed?
b
Can the plant perform photosynthesis without a large supply of carbon dioxide?
d
Can the plant perform photosynthesis without a large supply of oxygen?
The TWO questions that this investigation is designed to answer are:
a. Can the plant perform respiration without a large supply of oxygen?
d. Can the plant perform photosynthesis without a large supply of oxygen?
The two questions that this investigation is designed to answer are:
a. Can the plant perform respiration without a large supply of oxygen?
d. Can the plant perform photosynthesis without a large supply of oxygen?
To answer these questions, the student sets up an experiment by completely sealing a plastic bag over a plant. By doing so, she prevents the entry of external oxygen into the bag. Over a period of time, the student observes the plant to see if it remains green and healthy, which would indicate that the plant is still able to perform respiration and photosynthesis even without a large supply of oxygen.
