• B. Respiration takes place only during the night.
• C. Respiration takes place during both day and night.
• D. Respiration takes place only when plants are not making food.

Answer 1

The correct option is C Respiration takes place during both day and night.

In respiration, plants use oxygen, and carbon dioxide is released. Respiration and photosynthesis both occur during the day. However, at night only respiration occurs which consumes oxygen.
