Question

which molecule is a product of photosynthesis?
a. nitrogen
b. water
c. sugar
d. carbon dioxide

Explanation:

Photosynthesis is the process by which plants use sunlight, carbon dioxide ($CO_2$) and water ($H_2O$) to produce glucose (a type of sugar, $C_6H_{12}O_6$) and oxygen ($O_2$). The chemical equation for photosynthesis is $6CO_2 + 6H_2O+light
ightarrow C_6H_{12}O_6 + 6O_2$. Nitrogen ($N_2$) is not directly involved in the photosynthesis reaction as a product. Water and carbon dioxide are reactants, not products, in the photosynthesis process.

Answer:

C. Sugar
