Do potted plants actually "aerate" rooms to any significant degree?

I see it mentioned in some books and movies and such, but does a single potted plant make much of a difference in a room at all? Or perhaps in large numbers?

It will make essentially no difference.  The effect will be, in any event, generally much smaller than the effect you have of depleting the oxygen in the room in the first place.  Which, unless you happen to live in a sealed environment for a long time, is very small.

And of course the plant also respires, so if there's not enough light at a given moment the plant actually takes oxygen from the air also.
