During an experiment, Harry enclosed two leaves of a plant in glass flasks labeled A and B. Flask A had water and carbon dioxide. Flask B had potassium hydroxide solution to absorb carbon dioxide. Harry kept the plants in sunlight and watered them every day.

Question

Which statement best describes the result of this experiment?

The leaf in flask A will not get oxygen to make glucose.
The leaf in flask A will convert water into carbon dioxide.
The leaf in flask B will not get carbon dioxide to make glucose.
The leaf in flask B will remove the carbon dioxide produced.

Answer 1

The statement that best describes the result of this experiment is:

The leaf in flask B will not get carbon dioxide to make glucose.

In flask A, the plant has access to both water and carbon dioxide, allowing it to perform photosynthesis and produce glucose and oxygen. In flask B, the potassium hydroxide solution absorbs carbon dioxide, meaning the leaf in this flask cannot use carbon dioxide for photosynthesis, which is essential for glucose production.
