    your biology teacher is not incorrect. you'd have to be in a major-oriented botany course to completely grasp photosynthesis and cellular respiration.
    here's a small summary: during the day while
    photosynthesis is happening in the leaves of plants, carbon dioxide is expelled from the air and used to make sugars. At night, when
    photosynthesis is not occuring and there is no sunlight for energy - respiration, as I stated earilier, is what occur and emits carbon dioxide.
    what's important though, is that plants are requiews to take up much more carbon dioxide in photosynthesis
    than they give off in respiration at night.
    Plants generate carbon dioxide by combining glucose with oxygen in many intricate phases to make carbon dioxide and water.
