Question

Question 12 A student sets up an investigation by placing a plastic bag over a plantShe 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 e Can the plant perform respiration faster than a plant that is not sealed? Can the plant perform photosynthesis without a large supply of carbon dioxide? Can the plant perform respiration without a large supply of carbon dioxide? Can the plant perform photosynthesis faster than a plant that is not sealed? Can the plant perform photosynthesis without a large supply of oxygen?

Answer 1

The investigation set up by the student, where a plant is placed in a sealed plastic bag, is designed to explore the effects of limited gas exchange on the plant's ability to perform certain processes. Given the context, the two questions that this investigation is likely aimed at answering are:

1. Can the plant perform photosynthesis without a large supply of carbon dioxide? - Since the bag is sealed, the plant may not have enough carbon dioxide to carry out photosynthesis effectively.

2. Can the plant perform respiration without a large supply of oxygen? - The sealed environment may restrict the oxygen available for respiration.

Thus, the two questions are:

• Can the plant perform photosynthesis without a large supply of carbon dioxide?
• Can the plant perform respiration without a large supply of oxygen?
