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 carbon dioxide?
b
Can the plant perform photosynthesis faster than a plant that is not sealed?
c
Can the plant perform photosynthesis without a large supply of carbon dioxide?
d
Can the plant perform photosynthesis without a large supply of oxygen?
e
Can the plant perform respiration faster than a plant that is not sealed?
f
Can the plant perform respiration without a large supply of oxygen?
The investigation, as described, is designed to answer the following two questions:
c) Can the plant perform photosynthesis without a large supply of carbon dioxide?
e) Can the plant perform respiration faster than a plant that is not sealed?
The investigation described is designed to answer the following two questions:
1. Can the plant perform photosynthesis without a large supply of carbon dioxide?
2. Can the plant perform respiration without a large supply of oxygen?
To arrive at these answers, the student is observing the plant daily to see if it remains green and healthy despite being sealed in a plastic bag. By monitoring the plant's condition, the student can determine whether photosynthesis (the process by which plants convert carbon dioxide into energy using sunlight) and respiration (the process by which plants convert oxygen into energy) are still occurring, even without a regular supply of these gases.
The two questions that this investigation is designed to answer are:
b) Can the plant perform photosynthesis faster than a plant that is not sealed?
c) Can the plant perform photosynthesis without a large supply of carbon dioxide?
