Best Answer

Plants give out oxygen (from the breakdown of water) and take in carbon dioxide, which they use to form carbohydrates in the process of photosynthesis.

However, at night and in darker conditions, plants still need energy, and use cellular respiration as animals do, taking in some oxygen and releasing carbon dioxide. This is normally much less chemical activity than photosynthesis, so green plants release much more oxygen than they use.
