Which gas do plants take from the atmosphere for photosynthesis?
Answer and explanation
Correct answer: Carbon dioxide
The governing concept is photosynthesis. Green plants use carbon dioxide from the air, water from the soil, and light energy to manufacture glucose in their leaves; oxygen is released as a by-product. Therefore, carbon dioxide is correct. Oxygen is mainly involved in respiration, nitrogen is not directly absorbed from air for ordinary photosynthesis, and ozone is a reactive protective gas rather than the required raw material.
