Why does photosynthesis require water?
A. Because water provides oxygen atoms
B. Because water provides electrons
C. Because water accepts electrons
D. Because water acts as a catalyst
Answer (2)
B. because water provides electrons Water supplies the necessary electrons during the light reaction by a process called photolysis of water .
Water is essential in photosynthesis because it supplies electrons that replace those lost from chlorophyll during light-dependent reactions. Additionally, it produces oxygen as a byproduct and contributes to the formation of ATP, which is crucial for the subsequent stages of photosynthesis. Thus, the correct answer is B. Because water provides electrons.
