Question

during photosynthesis, water and carbon dioxide become glucose and oxygen.
true
false

Explanation:

The process of photosynthesis in plants (and some other organisms) uses carbon dioxide ($\ce{CO_2}$) and water ($\ce{H_2O}$) in the presence of light energy to produce glucose ($\ce{C_6H_{12}O_6}$) and oxygen ($\ce{O_2}$). The chemical equation for photosynthesis is $6\ce{CO_2} + 6\ce{H_2O} \xrightarrow[\text{Chlorophyll}]{\text{Light}} \ce{C_6H_{12}O_6} + 6\ce{O_2}$, which confirms that water and carbon dioxide are converted into glucose and oxygen during photosynthesis.

Answer:

True
