Answer:
Yes, the statement is correct. Plants respire throughout the day, while photosynthesis takes place only in the presence of sunlight. ... At night, when there is no photosynthesis, no oxygen is released. Also, CO2 produced during respiration is not used by the plants

No.
Because photosynthesis occurs during day time (presence of sunlight) . During this time oxygen is released. Some oxygen used for respiration and the rest diffused into the air.
Carbon dioxide also released during this time used for photosynthesis. But at night time there's no photosynthesis , no oxygen evolved. Carbon-di-oxide produced during respiration diffuses into air.
So, the carbon-di-oxide is released not only in night time but all time.
