Green plants carry on respiration
Correct answer: C. During both day and night
- A. Only during the day
- B. Only at night
- C. During both day and night
- D. Only when photosynthesis is going on
Explanation
Respiration is the process by which cells generate energy from glucose and oxygen, and it is a continuous metabolic activity necessary for the plant's survival. While photosynthesis primarily occurs during the day when there is light available, respiration occurs 24/7 because plants need energy both for their daytime activities and to support basic functions like growth and maintenance during the night when there is no sunlight for photosynthesis. Therefore, plants respire both during the day and at night to maintain their life processes.
