Which gas do plants mainly take in during photosynthesis?
Answer and explanation
Correct answer: Carbon dioxide
Photosynthesis uses carbon dioxide from the atmosphere and water from the soil to produce glucose, with light energy captured by chlorophyll. Thus carbon dioxide is the principal gas taken in for carbon fixation, making option B correct. Oxygen is mainly released as a product, nitrogen is not the chief gaseous raw material in this equation, and free hydrogen is not normally taken in by green plants for photosynthesis.
