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.
Both photosynthesis and respiration processes occurs at the same time in the plant body.
Explanation:
In cellular respiration, food molecules such as glucose are broken down for the production of energy in the form of Adenine tri phosphate, water and carbondioxide gas. This carbondioxide and water is used in the plants during the process of photosynthesis in which glucose and oxygen are produced. Glucose is stored in different parts of plant body and oxygen is released in the atmosphere through stomata. So that's why plants released oxygen not carbondioxide.
