Be careful with this question.
Plants do both photosynthesis and cellular respiration.
-- In photosynthesis plants take in carbon dioxide and release oxygen.
-- In celluar respiration they use oxygen and release carbon dioxide, just like we do.
Humans do cellular respiration (to get energy to run our cells), but we can never do photosynthesis. So we take in oxygen and release carbon dioxide.

humans will always release carbondioxide but plants release oxygen in the day and carbon dioxide at night

Plants "breath" in carbon dioxide, and "exhale" oxygen.
Humans breath in oxygen, and breath out carbon dioxide.
