Question

which gas do plants absorb from the atmosphere during photosynthesis?
○ sulfur
○ oxygen
○ nitric oxide
○ carbon dioxide

Explanation:

Photosynthesis is the process by which plants use light energy to convert carbon dioxide ($CO_2$) and water ($H_2O$) into glucose ($C_6H_{12}O_6$) and oxygen ($O_2$). The chemical equation for photosynthesis is

$$6CO_2 + 6H_2O+light\ energy ightarrow C_6H_{12}O_6 + 6O_2$$

. Sulfur is not a gas involved in the main photosynthesis reaction. Plants release oxygen as a by - product of photosynthesis, not absorb it. Nitric oxide ($NO$) is not a reactant in the photosynthesis process. Carbon dioxide is taken in by plants from the atmosphere for photosynthesis.

Answer:

carbon dioxide
