I'm working on a lab to show that light reactions must occur prior to dark reactions in photosynthesis.

so far, i thought of the experiment involving two plants, one exposed to sunlight, the other is kept in a box. both receive the same amount of water soil, etc and both are the same type of plant. would this actually prove that light reactions occur first though?
i'm kinda at a loss for what to do.

  1. I don't know how you will measure these reactions, but possibly you might show what needs to occur first by using an "ABBA" arrangement with one plant and a "BAAB" arrangement with the other.

    A = sunlight
    B = no sunlight

    However, one plant under each condition is not a large enough sample for statistical analysis.

    I hope this helps. Thanks for asking.
