Question

Quizplus · Accepted Answer

Stomata allow for the entry of carbon dioxide, which is used in the Calvin cycle for photosynthesis. They also allow for the exit of oxygen that is produced during photosynthesis. Option B is incorrect because oxygen is not used in the Calvin cycle. Option C is incorrect because stomata do not remove water and carbon dioxide, but rather allow for their exchange. Option D is incorrect because stomata do not remove nitrogen-containing waste products.
