Plants absorb carbon dioxide from the atmosphere during photosynthesis, not sulfur, oxygen, or nitric oxide.

Correct option

  • The correct answer to the question “which gas do plants absorb from the atmosphere during photosynthesis? sulfur oxygen nitric oxide carbon dioxide” is: carbon dioxide.

Quick explanation

  • During photosynthesis, green plants take in carbon dioxide CO2CO₂CO2​ from the air through tiny pores on their leaves called stomata.
  • Using sunlight and water, they convert this carbon dioxide into glucose (a sugar) and release oxygen as a byproduct.

Why not the other options?

  • Oxygen : Mostly released during photosynthesis rather than absorbed; it is mainly used by plants during respiration, not as the primary input for photosynthesis.
  • Sulfur and nitric oxide : These are not the main gases used in photosynthesis; plants may interact with such compounds in other physiological or environmental processes, but they are not the key atmospheric gas taken in for photosynthesis.
