Question

the reactants for photosynthesis are multiple choice water and oxygen. oxygen and carbon dioxide. water and carbon dioxide. atp and oxygen

Explanation:

Photosynthesis is the process by which plants use light energy to convert reactants into glucose and oxygen. The chemical equation for photosynthesis is \(6CO_2 + 6H_2O \xrightarrow{\text{light energy}} C_6H_{12}O_6 + 6O_2\). From this equation, the reactants (substances used) are carbon dioxide (\(CO_2\)) and water (\(H_2O\)). The first option has oxygen (a product), the second has oxygen (a product) and carbon dioxide, the fourth has ATP (involved in cellular respiration/energy transfer, not a main reactant of photosynthesis) and oxygen (a product). So the correct reactants are water and carbon dioxide.

Answer:

C. water and carbon dioxide (assuming the third option is labeled C; if the original options had labels like A, B, C, D with the third being C, then the answer is C. water and carbon dioxide)
