Final answer:
Plants undergo photosynthesis during the day, using carbon dioxide and water to produce glucose and oxygen. At night, they undergo cellular respiration, using oxygen and glucose to produce carbon dioxide, water, and energy. This continuous cycle helps plants generate energy and maintain the oxygen-carbon dioxide balance in the atmosphere.
Step-by-step explanation:
Plants undergo a process called photosynthesis during the day. They use carbon dioxide and water, along with energy from sunlight, to produce glucose (sugar) and oxygen. However, at night when there is no sunlight, plants go through a process called cellular respiration. During cellular respiration, they use oxygen and glucose to produce carbon dioxide, water, and energy.
This continuous cycle of photosynthesis and cellular respiration helps plants generate energy and maintain the oxygen-carbon dioxide balance in the atmosphere. Plants undergo photosynthesis during the day, using carbon dioxide and water to produce glucose and oxygen. At night, they undergo cellular respiration, using oxygen and glucose to produce carbon dioxide, water, and energy. This continuous cycle helps plants generate energy and maintain the oxygen-carbon dioxide balance in the atmosphere.
