Would there be more, less or the same amount of oxygen in a container with a plant in it overnight?

A healthy plant is placed in a sealed container overnight, when the plant is in darkness. The concentration of oxygen in the trapped air is measured at the start of the night and again in the morning. Would there be more, less or the same amount of oxygen in the container in the morning?

    Plants breathe in oxygen at night so there will be less oxygen since there is no light to photosynthesize at night.

    Generally, "Less, because the plant is continuing aerobic cellular respiration and thus using up some oxygen.  The plant is not producing oxygen because the light-dependent reactions of photosynthesis are not occurring in the dark."

    Think about what is required for a plant to (a) create oxygen or (b) consume oxygen.

    Which does it do more of during the night?
