Answer 2

O2 is produced by plants during the so-called "light reactions". Plants basically use light energy to "break" water (H2O) into O2 and H+. Thus, no plant produces O2 during the night, no matter which type of photosynthesis it does. If you are worried about your health, don't! The O2 in air is so abundant (21%), that the effect of your home plants is almost negligible.
