Photosynthesis and Respiration:
Whilst Photosynthesis requires carbon dioxide and releases oxygen to produce glucose, respiration needs oxygen while inhaling and releases carbon dioxide while exhaling. Photosynthesis happens during the day time when the sun shines because the plants require sunlight to produce energy and respiration happens continuously. But unlike other living creatures plants breathe once in a day. During night, when there is no sunlight, stomata are closed and the leaves breathe releasing carbon dioxide in the air.
