    In a typical sunny day, does a healthy green plant produced more oxygen, during photosynthesis, than its intake of oxygen during the dark night ? If this is true, green plants are actually producing a surplus of oxygen to the environment throughout its entire lifetime ?

    Your use of the word 'surplus' implies that plants use oxygen, as far a I know the production of oxygen by plants is merely a waste product of removing carbon from the atmosphere. You might like to go and look up 'the carbon cycle'. Your question has the look of a disguised homework question and so it will not be answered directly. We do give help with homework, but only where you may be stuck on a particular point eg something you have read but require further explanation, or where you may need help to constructively phrase your own findings in a logical fashion.

    Of course plants use oxygen! Plants have mitochondria just like me an you!

    TO answer your question, yes. Plants do make more oxygen than they use. If not ... we would be running out of oxygen!

    It depends on what type of photosynthesis they're doing... they could be C3, C4 or CAM types....
