EVERYDAY SCIENCE

Detailed explanation-1: -Respiration must not be mistaken for photosynthesis. 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-2: -(c) Respiration takes place both during day and night.

Detailed explanation-3: -Plants respire in both day and night same as human being and photosynthesis only occurs during the day.

Detailed explanation-4: -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-5: -Plants respire both during day and by night. However, during the day, the amount of oxygen given out by the plant through the process of photosynthesis far exceeds the amount of oxygen used by the plant for respiration.
