Hmmm... Not sure I understand the question. All plants give off oxygen as part of the process of photosynthesis. So I guess the answer is 'NO' as they don't photosynthesize at night. In fact, plants use oxygen at night. Luckily, they produce more during the day than they use at night.

Welcome to NGA, shobhit!

I agree with Daisy. For a plant to produce oxygen at night, you would have to shine a bright light on it. And not all plants would be happy with 24-hour sun.
