All plants give out oxygen during day carbon dioxide during night . Do you agree with this statement ? Give reason

Explanation

Plants perform two processes all together, photosynthesis and respiration. Photosynthesis takes place during day time when there is enough sunlight. During this process, the green tissue of the plants exposed to light makes glucose in presence of chlorophyll pigment, water and carbon dioxide. During this process oxygen is released and it is possible only in presence of sunlight.
Respiration is another process which is carried out by all animals or plants. This is a continuous process where glucose is broken down to `CO_2 and H_2O` and either photosynthesis is not taking place or its rate energy is released in the form of ATP molecules. This is continued regardless of daylight or darkness.
