NEET BIOLOGY

Detailed explanation-1: -Plants release oxygen during the day in the presence of natural light through the process of photosynthesis. While at night, the plants uptake oxygen and release carbon dioxide, which is called respiration.

Detailed explanation-2: -At night, or in the absence of light, photosynthesis in plants stops, and respiration is the dominant process. The plant uses energy from the glucose it produced for growth and other metabolic processes.

Detailed explanation-3: -These plants do release some oxygen at night when the stomata open and the oxygen can escape. Carbon dioxide is not released during photosynthesis, but small amounts of that gas are emitted both day and night as a by-product of cellular respiration.

Detailed explanation-4: -Respiration occurs all through the day, but the photosynthesis process occurs in the daytime, in the presence of sunlight only. Consequently, respiration becomes evident at night time in plants.

Detailed explanation-5: -Plants respire in both day and night same as human being and photosynthesis only occurs during the day.
