Which gas do plants mainly take in for photosynthesis?

Answer and explanation

Correct answer: Carbon dioxide

The governing concept is the raw-material requirement of photosynthesis. Plants take in carbon dioxide from the atmosphere through stomata, while water comes mainly from the roots. Using light energy and chlorophyll, carbon dioxide contributes carbon to the carbohydrates formed. Thus option A is correct; oxygen is mainly released as a product, and nitrogen or hydrogen gas is not the principal gas taken in for this process.
