CO₂enters and O₂ escapes from a leaf via A) stomata. B) thylakoids. C) grana. D) stroma.

Question

Quizplus · Accepted Answer

Stomata are small openings in the leaf surface through which CO2 enters and O2 escapes during photosynthesis. Thylakoids and grana are both part of the membrane structure within chloroplasts where photosynthesis occurs, but they do not directly participate in gas exchange. The stroma is a fluid-filled space within the chloroplast, but it is not directly involved in gas exchange either.
