    He takes soda water in a glass tumbler and add a chlorophyll into the contents and keeps the tumbler exposed to sunlight hoping that he has provided necessary ingredients for photosynthesis to proceed (viz.\[C{{O}_{2}}\,\,\,{{H}_{2}}O\] chlorophyll and light). What do you think what happen after say a few hours of exposers of light?

    A) Photosynthesis will take place and glucose will be produced

    B) Photosynthesis will take place and starch will be produced which turn the mixture turbid

    C) Photosynthesis will not take place because \[C{{O}_{2}}\] dissolved in soda water escapes into the atmosphere

    D) Photosynthesis will not take place because intact chloroplasts are needed for the process
