    Which of the following absorb light energy for photosynthesis?

    A)  Chlorophyll       

    B)         Water molecule

    C)  \[{{O}_{2}}\]                                    

    D)  Ku BP

    Correct Answer: A

    Solution :

    Obviously, it is chlorophyll which absorbs light for photosynthesis. \[{{H}_{2}}O\] molecules provide H+ ions and electrons during photosynthesis. \[{{O}_{2}}\] is liberated during photosynthesis. RuDP (Ribulose 1, 5-diphosphate) reacts with \[C{{O}_{2}}\] during dark reaction of photosynthesis. This process takes place in the presence of enzyme Rubisco.
