Step-by-step explanation:
Plants are characterized by photosynthesis in the day. Photosynthesis is characterized by being a process of formation of oxygen in addition to carbohydrates through the use of carbon dioxide, water and sunlight, in addition to the use of chlorophyll. While respiration is the opposite process of photosynthesis. During respiration, plants need oxygen, since it is used for the breakdown of carbohydrates to produce energy. Plants are characterized by storing a small amount of oxygen, for use during respiration. In this way, plants release oxygen during the day and the opposite occurs at night.
