Question

what are the reactants of photosynthesis? water and oxygen carbon dioxide and oxygen oxygen and glucose carbon dioxide and water

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 reactants are the substances that start the chemical reaction. In the photosynthesis equation \(6CO_2 + 6H_2O \xrightarrow{light} C_6H_{12}O_6+6O_2\), carbon dioxide and water are the reactants. Oxygen is a product, not a reactant (eliminating options with oxygen as a reactant like water and oxygen, carbon dioxide and oxygen). Glucose is also a product (eliminating oxygen and glucose).

Answer:

carbon dioxide and water
