Which of the following statements BEST describes the relationship between photosynthesis and respiration in plants at night?
Photosynthesis and respiration both cease, maintaining a neutral balance of gases.
Photosynthesis continues at a reduced rate, while respiration increases to compensate.
Photosynthesis ceases, and respiration also ceases to conserve energy.
