Do Houseplants give off carbon dioxide?

[Edit]

Answer

No -- in fact, houseplants, and any green plant, absorb carbon di-oxide (Co2) and produce oxygen.

actually... they do but during the day they absorb more then they produce and produce oxygen but during the night they give off carbon dioxide whch is why all flowers are removed from bed sides in hospitals during the night.
