Question

alice was participating in a photosynthesis lab for science class. the lab procedures instructed alice to prepare a test tube containing water, a sprig of elodea (a common aquarium plant), and 10 g of sodium bicarbonate (nahco3). she was then instructed to place the test tube in front of a strong light source for one minute. alice noticed tiny bubbles forming on the leaves of the elodea. what is the most logical explanation for why alice saw bubbles forming on the leaves of the elodea? a the bubbles formed as a result of the hydrogen from the sodium bicarbonate mixture dissolving the elodea leaves. b the bubbles formed from the release of water molecules from the elodea leaves. c the bubbles formed as the elodea plant released oxygen from the elodea leaves. d the bubbles formed as the elodea plant released carbon dioxide from the elodea leaves.

Explanation:

The lab involves photosynthesis, a process where plants use light energy to convert CO₂ and water into glucose and oxygen. Sodium bicarbonate provides CO₂. The bubbles observed are oxygen, a byproduct of photosynthesis released by the elodea leaves under light.

Answer:

C. The bubbles formed as the elodea plant released oxygen from the elodea leaves.
